Description

[0001] This application claims priority to the prior art patent application filed by the applicant on September 22, 2022 with the China National Intellectual Property Administration, application number 202211161020.8, entitled "Triharbine Base Derivatives and Pharmaceutical Compositions Thereof, Preparation Methods and Uses Thereof", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to thiamethoxam alkaloid derivatives and their pharmaceutical compositions, preparation methods and uses, belonging to the field of pharmaceutical compounds. Background Technology

[0003] Harringtonine alkaloids, such as homoharringtonine (HT), deoxyharringtonine (DHT), and isoharringtonine (IHT), are known anticancer drugs.

[0004]

[0005] Homoharringtonine 2 was included in the Chinese Pharmacopoeia in 1990 for the clinical treatment of acute non-lymphocytic leukemia and has been used clinically ever since.

[0006] Currently, medicinal cephalotaxine alkaloids are isolated from plants of the *Cephalotaxus* genus. However, natural cephalotaxine alkaloids constitute only a small portion of total alkaloids, and are primarily found in the non-renewable parts of the plant. Besides existing in low concentrations in natural plant materials, cephalotaxine alkaloids also mix with many structurally similar congeners, making the isolation of high-purity cephalotaxine alkaloids from natural products extremely difficult. Furthermore, due to the drastic decline in the number of *Cephalotaxus* plants, which have become rare and protected species, the isolation of cephalotaxine alkaloids from plants is far from meeting the needs of clinical applications.

[0007] The inventor previously obtained a Chinese patent ZL201510925650.1 that reported a class of cephalotaxine alkaloids, their synthesis methods and uses, in which some of the compounds in the examples showed certain inhibitory activity against HL-60 human leukemia cells.

[0008] Currently, further research is needed on derivatives of these compounds in order to develop drug compounds with improved anticancer activity. Summary of the Invention

[0150] When administered as a medicine, the compounds of the present invention may be given in the form of pharmaceutical compositions. These compositions may be prepared in a manner well known in the pharmaceutical field and may be administered via a variety of routes, depending on whether local or systemic treatment is required and the area to be treated. Administration may be local (e.g., transdermal, skin, eye, and mucous membrane delivery, including intranasal, vaginal, and rectal delivery), pulmonary (e.g., by inhalation or blowing of powders or aerosols, including via nebulizers; intratracheal, intranasal), oral, or parenteral. Parenteral administration includes intravenous, intra-arterial, subcutaneous, intraperitoneal, or intramuscular injection or infusion; or intracranial, such as intrathecal or intraventricular administration. Parenteral administration may be in the form of a single large dose or via, for example, a continuous infusion pump. Topically administered pharmaceutical compositions and formulations may include transdermal patches, ointments, lotions, creams, gels, drops, suppositories, sprays, liquids, powder formulations, and powders. Conventional drug carriers, water, powder or oily bases, thickeners, etc., may be necessary or required.

[0151] In preparing the compositions of the present invention, the active ingredient is typically mixed with an excipient, diluted by the excipient, or contained in a carrier such as a capsule, pouch, paper, or other container. When the excipient is used as a diluent, it can be a solid, semi-solid, or liquid substance, serving as a solvent, carrier, or medium for the active ingredient. Therefore, the compositions can be in the following forms: tablets, pills, powders, lozenges, pouches, capsules, elixirs, suspensions, emulsions, solutions, syrups, aerosols (solid or soluble in a liquid solvent); ointments containing, for example, up to 10% by weight of the active compound; soft and hard gelatin capsules; suppositories; sterile injectable solutions; and sterile packaged powders.

[0152] Some examples of suitable excipients include lactose, glucose, sucrose, sorbitol, mannitol, starch, gum arabic, calcium phosphate, alginate, tragacanth gum, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water, syrup, and methylcellulose. Formulations may also contain: lubricants such as talc, sodium stearate, magnesium stearate, sodium oleate, sodium benzoate, sodium acetate, sodium chloride, and mineral oil; humectants; emulsifiers and suspending agents; preservatives such as methyl benzoate and hydroxypropyl benzoate; sweeteners and flavoring agents. The compositions of the present invention can be formulated using methods known in the art to provide immediate, sustained, or delayed release of the active ingredient upon administration to a patient.

[0153] Compositions can be formulated in unit dosage forms, each containing approximately 5 to 1000 mg, more typically approximately 100 to 500 mg of active ingredient. The term "unit dosage form" refers to a physically isolated single-dose unit suitable for use in human patients and other mammals, each unit containing a predetermined amount of active substance, calculated to produce the desired therapeutic effect, when mixed with suitable pharmaceutical excipients.

[0154] The effective dose range of an active compound can be quite wide, and it is usually administered at the pharmaceutically effective dose. However, it is understood that the actual amount of compound administered is usually determined by the physician based on relevant circumstances, including the condition being treated, the route of administration chosen, the actual compound administered, the patient's age, weight, and response, and the severity of the patient's symptoms.

[0155] For the preparation of solid compositions, such as tablets, the main active ingredient is mixed with a pharmaceutical excipient to form a solid preform composition containing a homogeneous mixture of the compounds of the present invention. When these preform compositions are referred to as homogeneous, it means that the active ingredient is generally uniformly distributed throughout the composition, such that the composition can be readily divided into equally effective unit dosage forms, such as tablets, pills, and capsules. The solid preform is then divided into unit dosage forms of the type described above, containing, for example, about 0.1 to 1000 mg of the active ingredient of the present invention.

[0156] The tablets or pills of this invention can be coated or compounded to obtain dosage forms that provide the advantage of long-lasting action. For example, the tablets or pills contain an internal dose and an external dose component, the latter being a coated form of the former. The two components can be separated by an enteric coating layer, which is used to prevent disintegration in the stomach, allowing the internal component to pass through the duodenum intact or to delay release. A variety of substances can be used for such enteric coatings or coatings, including a variety of high molecular weight acids and mixtures of high molecular weight acids with such substances such as shellac, cetyl alcohol, and cellulose acetate.

[0157] The compounds and compositions of the present invention may be incorporated into liquid forms for oral or injectable administration, including aqueous solutions, suitably flavored syrups, water or oil suspensions; and emulsions flavored with edible oils such as cottonseed oil, sesame oil, coconut oil or peanut oil; as well as elixirs and similar pharmaceutical solvents.

[0158] Compositions for inhalation or inhalation include solutions and suspensions, and powders, dissolved in pharmaceutically acceptable water or organic solvents or mixtures thereof. Liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described above. In some embodiments, the composition is administered orally or via nasal inhalation to achieve local or systemic effects. The composition can be nebulized using an inert gas. The nebulized solution can be inhaled directly from a nebulizer, or the nebulizer can be connected to a face mask or intermittent positive pressure ventilation machine. Solutions, suspensions, or powder compositions can be administered orally or nasally by a device that delivers the formulation in a suitable manner.

[0159] The amount of compound or composition given to a patient is not fixed and depends on the drug being administered, the purpose of administration (e.g., prevention or treatment), the patient's condition, the method of administration, etc. In therapeutic applications, a sufficient amount of the composition may be given to a patient with an existing disease to cure or at least partially suppress the symptoms of the disease and its complications. The effective dose should depend on the disease state being treated and the judgment of the attending clinician, which depends on factors such as the severity of the disease, the patient's age, weight, and general condition.

[0160] The compositions administered to patients may be in the form of the pharmaceutical compositions described above. These compositions may be sterilized using conventional sterilization techniques or filterable sterilization. The aqueous solutions may be used as is, or lyophilized; prior to administration, the lyophilized formulation may be mixed with a sterile aqueous carrier. The pH of the compound formulation is typically 3–11, more preferably 5–9, and most preferably 7–8. It is understood that the use of certain of the aforementioned excipients, carriers, or stabilizers may result in the formation of drug salts.

[0161] The therapeutic dose of the compounds of this invention may be determined based on, for example, the specific therapeutic use, the manner of administration of the compound, the patient's health and condition, and the prescribing physician's judgment. The proportion or concentration of the compounds of this invention in the pharmaceutical composition may not be fixed and depends on a variety of factors, including dosage, chemical properties (e.g., hydrophobicity), and route of administration. For example, the compounds of this invention may be provided in a physiologically buffered aqueous solution containing about 0.1 to 10% (w / v) of the compound for parenteral administration. Some typical dosage ranges are from about 1 μg / kg to about 1 g / kg body weight / day. In some embodiments, the dosage range is from about 0.01 mg / kg to about 100 mg / kg body weight / day. The dosage is likely to depend on variables such as the type and severity of the disease or condition, the general health status of the specific patient, the relative biological potency of the selected compound, the excipient formulation, and the route of administration. The effective dose can be obtained by extrapolation from dose-response curves derived from in vitro or animal model testing systems.

[0162] The present invention provides the use of at least one of the compounds of formula (I), their racemates, stereoisomers, tautomers, isotope labels, N-oxides, hydrates, solvates, polymorphs, metabolites, pharmaceutically acceptable salts, pharmaceutically acceptable esters, or prodrug compounds in an analytical test for identifying compounds capable of inhibiting one or more tumor cells.

[0163] More preferably, the competitive binding assay includes contacting the compound of the invention with tumor cells and detecting any changes in the interaction between the compound of the invention and the tumor cells.

[0175] Unless otherwise defined, the term "3-20 membered heterocyclic group" refers to a saturated or unsaturated non-aromatic ring or ring system, for example, a 4-, 5-, 6-, or 7-membered monocyclic ring, a 7-, 8-, 9- or 7-membered bicyclic ring (such as a fused ring, bridged ring, or spirocyclic ring), or a 10-membered tricyclic ring system, and contains at least one, for example, 1, 2, 3, 4, 5, or more heteroatoms selected from O, S, and N, wherein N and S may optionally be oxidized to various oxidation states to form nitrogen oxides, -S(O)-, or -S(O)2- states. Preferably, the heterocyclic group may be selected from "3-10 membered heterocyclic groups". The heterocyclic group may be connected to the rest of the molecule by any one of the carbon atoms or a nitrogen atom (if present). The heterocyclic group may include fused or bridged rings and spirocyclic rings. Specifically, the heterocyclic group may include, but is not limited to: 4-membered rings, such as azirrobutyl and oxobutyl; 5-membered rings, such as tetrahydrofuranyl, dioxacyclopentenyl, pyrrolyl, imidazoyl, pyrazolyl, or pyrrololinyl; or 6-membered rings, such as tetrahydropyranyl, piperidinyl, morpholinyl, dithiaalkyl, thiomorpholinyl, piperazinyl, or trithiaalkyl; or 7-membered rings, such as diazacycloheptyl. Optionally, the heterocyclic group may be benzofused. The heterocyclic group may be bicyclic, for example, but not limited to, 5,5-membered rings, such as hexahydrocyclopenta[c]pyrrolo-2(1H)-yl rings, or 5,6-membered bicyclic rings, such as hexahydropyrrolo[1,2-a]pyrazin-2(1H)-yl rings. The heterocyclic group can be partially unsaturated, meaning it can contain one or more double bonds, such as, but not limited to, dihydrofuranyl, dihydropyranyl, 2,5-dihydro-1H-pyrroleyl, 4H-[1,3,4]thiadiazinyl, 4,5-dihydrooxazolyl, or 4H-[1,4]thiazinyl. Alternatively, it can be benzofused, such as, but not limited to, dihydroisoquinolinyl. When the 3-10 membered heterocyclic group is linked to other groups to form the compounds of the present invention, the carbon atom on the 3-10 membered heterocyclic group can be linked to other groups, or the heterocyclic atom on the ring of the 3-10 membered heterocyclic group can be linked to other groups. For example, when the 3-10 membered heterocyclic group is selected from piperazineyl, the nitrogen atom on the piperazineyl group can be linked to other groups. Or when the 3-10 membered heterocyclic group is selected from piperidinyl, the nitrogen atom on the piperidinyl ring and the carbon atom at its para position can be linked to other groups.

[0179] The term "fused ring" refers to a ring system in which two rings share two cyclic atoms.

[0180] The term "bridged ring" refers to a ring system in which two rings share three or more cyclic atoms.

[0181] Unless otherwise stated, heterocyclic, heteroaryl, or heteroaryl groups include all possible isomers, such as their positional isomers. Thus, for some illustrative, non-limiting examples, forms may include those in which one, two, or more of the following positions (if present): substituted or bonded to other groups, including pyridin-2-yl, pyridin-2-yl, pyridin-3-yl, pyridin-3-yl, pyridin-4-yl, and pyridin-4-yl; thiophene or thiophene groups including thiophene-2-yl, thiophene-2-yl, thiophene-3-yl, and thiophene-3-yl; and pyrazol-1-yl, pyrazol-3-yl, pyrazol-4-yl, and pyrazol-5-yl.

[0184] In the term "three (C)" 1-20 "alkyloxy)silyl" and the term "tris(C)" 1-20 In "alkyl)silyl", each C 1-20 Alkyl groups may be the same as or different from each other, and are independently selected from the definitions described above.

[0185] The abbreviations of groups used in this article have meanings well known in the art, such as Me for methyl, Et for ethyl, Ph for phenyl, TMS for trimethylsilyl, i-Pr for isopropyl, and Ac for acetyl.

[0186] Those skilled in the art will understand that the compounds shown in formula (I) can exist in the form of various pharmaceutically acceptable salts. If these compounds have a basic center, they can form acid addition salts; if these compounds have an acidic center, they can form base addition salts; if these compounds contain both an acidic center (e.g., a carboxyl group) and a basic center (e.g., an amino group), they can also form internal salts.

[0187] The compounds of the present invention may exist as solvates (such as hydrates), wherein the compounds of the present invention contain a polar solvent, particularly, for example, water, methanol, or ethanol, as a structural element of the lattice of the compound. The amount of the polar solvent, particularly water, may be stoichiometric or non-stoichiometric.

[0188] The compounds of the present invention can exist in the form of stereoisomers, which can be enantiomers and cis-trans isomers, or enantiomers and diastereomers.

[0189] Depending on their molecular structure, the compounds of the present invention can be chiral, and therefore may exist in various enantiomeric forms. Thus, these compounds can exist in racemic or optically active forms. The compounds of the present invention encompass isomers of each chiral carbon in the R or S configuration, or mixtures thereof, and racemates. The compounds of the present invention or their intermediates can be isolated as enantiomeric compounds by chemical or physical methods known to those skilled in the art, or used in this form for synthesis. In the case of racemic amines, diastereomers are obtained from the mixture by reaction with an optically active resolving agent. Examples of suitable resolving agents are optically active acids, such as tartaric acid in both R and S forms, diacetyltartaric acid, dibenzoyltartaric acid, mandelic acid, malic acid, lactic acid, suitable N-protected amino acids (e.g., N-benzoylproline or N-benzenesulfonylproline), or various optically active camphorsulfonic acids. Chromatographic enantiomeric separation can also be advantageously performed using optically active resolving agents (e.g., dinitrobenzoylphenylglycine immobilized on silica gel, cellulose triacetate or other carbohydrate derivatives, or chiral derivatized isobutylene ester polymers). Suitable eluents for this purpose are aqueous or alcoholic solvent mixtures, such as hexane / isopropanol / acetonitrile.

[0190] The term "cis-trans isomers" refers to isomers with different orientations of the substituent atoms associated with the carbon-carbon double bond. The substituent atoms (not H) on either side of the carbon-carbon double bond can be E or Z configurations. In the "E" (opposite) or "chair" configuration, the substituent is on the opposite side of the carbon-carbon double bond; in the "Z" (same-side) or "boat" configuration, the substituent is oriented on the same side of the carbon-carbon double bond. Compounds having a mixture of "cis" and "trans" configurations are designated as "cis / trans".

[0191] The symbols “R”, “S”, “E”, “Z”, “cis”, “trans”, etc., described in this article are used to indicate the atomic configuration relative to the core molecule and are used in the manner defined in IUPAC Recommendations for Fundamental Stereochemistry (Section E) (Pure Appl. Chem., 1976, 45:13-30).

[0192] Individual isomers of the compounds of this invention can be prepared by isomer-specific synthesis or by resolution of mixtures of isomers. Conventional resolution techniques include using optically active salts to form the free bases of each isomer in an isomer pair (followed by fractional crystallization and regeneration of the free base), using esters or amides to form the isomers in an isomer pair (followed by chromatographic separation and removal of chiral excipients), or using preparative TLC (thin-layer chromatography) or chiral HPLC columns to resolve mixtures of isomers of either the starting material or the final product.

[0193] The term "patient" refers to any animal, including mammals, preferably mice, rats, other rodents, rabbits, dogs, cats, pigs, cattle, sheep, horses, or primates, with humans being the most preferred.

[0194] The term “therapeutic effective dose” refers to the amount of an active compound or drug that researchers, veterinarians, physicians, or other clinicians are searching for in tissues, systems, animals, individuals, or humans to elicit a biological or medical response. It includes one or more of the following: (1) prevention of disease: e.g., prevention of disease, disorder, or condition in individuals susceptible to disease, disorder, or symptom but not yet experiencing or exhibiting the pathology or symptoms of the disease; (2) inhibition of disease: e.g., inhibition of disease, disorder, or symptom in individuals experiencing or exhibiting the pathology or symptoms of the disease, disorder, or symptom (i.e., prevention of further development of the pathology and / or symptoms); (3) relief of disease: e.g., relief of disease, disorder, or symptom in individuals experiencing or exhibiting the pathology or symptoms of the disease, disorder, or symptom (i.e., reversal of the pathology and / or symptoms). Therapeutic effective doses can initially be estimated by cell culture assays or by estimating the initial dose from in vivo data. Using these initial guidelines, those skilled in the art can determine the effective dose for humans. Furthermore, the toxicity and therapeutic efficacy of the compounds described herein can be determined by standard pharmaceutical procedures in cell cultures or laboratory animals, e.g., by determining the LD50. 50 and ED 50 .

[0195] Examples of the "excipients" described in this invention can be found in "Handbook of Pharmaceutical Excipients, 2nd Edition, 1994, edited by A Wade and PJ Weller".

[0196] The “carrier” or “diluent” described in this invention is well known in the pharmaceutical field and has been described, for example, in Remington’s Pharmaceutical Sciences, Mack Publishing Co. (ARGennaro, 1985).

[0197] The choice of drug carrier, excipient, or diluent can be made based on the intended route of administration and standard pharmaceutical practice. A pharmaceutical composition may contain, or additionally contain, any suitable binder, lubricant, suspending agent, coating agent, solubilizer, buffer, flavoring agent, surfactant, thickener, preservative (including antioxidants), etc., as a carrier, excipient, or diluent, and substances included to make the formulation isotonic with the recipient's blood.

[0198] For pharmaceutical formulations suitable for oral administration, where the carrier is solid, the most preferred form is a unit-dose formulation, such as pills, capsules, or tablets, each containing a predetermined amount of the active compound. Tablets can be prepared by compression or molding, optionally with one or more excipients. Compressed tablets can be prepared by compressing the active compound in a free-flowing form (such as powder or granules) in a suitable machine, optionally mixed with a binder, lubricant, inert diluent, lubricating substance, surfactant, or dispersant. Molded tablets can be prepared by molding the active compound and an inert liquid diluent. Tablets can optionally be coated, and if not coated, symbols can optionally be printed. Capsules can be prepared by filling the active compound alone or mixed with one or more excipients into a capsule shell and then sealing it in a conventional manner. Flat capsules are similar to capsules, wherein the active compound, along with any excipients, is sealed in a rice paper film. The active compound can also be formulated into dispersible granules, for example, which can be suspended in water or sprinkled on food before administration. Granules can be packaged, for example, in sachets. The carrier can be a liquid formulation suitable for oral administration, and can be presented as a solution or suspension in an aqueous or non-aqueous liquid form, or as an oil-in-water liquid emulsion.

[0199] The term "pharmaceutically acceptable salt" includes its suitable acid addition salt or base salt. For information on suitable pharmaceutical salts, see JPharm Sci, 66, 199, 1977, Berge et al.

[0200] The term "pharmaceutically acceptable ester" refers to an ester formed by the use of an organic acid or alcohol / hydroxide with an esterifiable functional group in the structure of the compounds of this invention.

Examples of such isotopes include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, and chlorine, as appropriate. 2 H, 3 H, 13 C 14 C 15 N、 17 O、 18 O、 31 P, 32 P, 35S, 18 F and 36 Cl. Using isotopes such as deuterium (i.e. 2 H) substitution can provide certain therapeutic advantages resulting from greater metabolic stability, such as increased in vivo half-life or reduced dose requirements, and may therefore be preferred in some cases. For example, the present invention includes compounds of general formula (I) in which any hydrogen atom is replaced by a deuterium atom.

[0202] The term "prodrug compound" refers to a covalently bonded compound that releases an active parent drug according to general formula (I) in vivo. Such prodrugs are typically compounds of the present invention in which one or more suitable groups have been modified such that the modification may be reversed upon administration to a human or mammalian subject. Reversal is usually achieved by enzymes naturally present in such subjects, although a second drug agent may be administered with this prodrug to facilitate reversal in vivo. Examples of such modifications include pharmaceutically acceptable esters as described above, where such reversal can be achieved by esterases, etc.

[0203] The term "polymorph" refers to the various crystalline, polycrystalline, and hydrated forms of the compounds of this invention. It is well known in the pharmaceutical industry that chemical compounds can be isolated in any of these forms by purification and / or separation of the solvents used in the synthetic preparation of such compounds.

[0204] The term "administration" indicates that the pharmaceutical compositions of the present invention are suitable for administration rectally, intranasally, intrabronchially, topically (including orally and sublingually), vaginally or parenterally (including subcutaneously, intramuscularly, intravenously, intra-arterially, and intradermally), intraperitoneally, or intrathecally. Preferably, the formulation is an orally administered formulation. The formulation can be conveniently presented in unit dosage forms, i.e., in the form of discrete portions comprising a unit dose or multiple units or subunits of a unit dose. As examples, the formulation can be in the form of tablets and sustained-release capsules, and can be prepared by any method well known in the pharmaceutical field.

[0205] The formulations for oral administration of the present invention may take the form of: discrete units, such as capsules, gels, drops, sachets, pills, or tablets, each containing a predetermined amount of an active agent; as powders or granules; as solutions, emulsions, or suspensions of the active agent in aqueous or non-aqueous liquids; or as oil-in-water or water-in-oil liquid emulsions; or as bolus formulations, etc. Preferably, each dose of these compositions contains 1 to 250 mg, more preferably 10 to 100 mg, of the active ingredient.

[0206] For compositions intended for oral administration (e.g., tablets and capsules), solvents and / or common excipients are also included, such as binders like syrups, gum arabic, gelatin, sorbitol, astragalus gum, polyvinylpyrrolidone (polyvinyl ether), methylcellulose, ethylcellulose, sodium carboxymethylcellulose, hydroxypropyl methylcellulose, sucrose, and starch; fillers and carriers such as corn starch, gelatin, lactose, sucrose, microcrystalline cellulose, kaolin, mannitol, dicalcium phosphate, sodium chloride, and alginate; and lubricants such as magnesium stearate, sodium stearate, and other metal stearates, glyceryl stearate, stearic acid, silicone fluids, talc, oils, and colloidal silica. Flavoring agents such as peppermint, wintergreen oil, and cherry flavoring may also be used. Coloring agents may be added to make the dosage form easily identifiable. Tablets may also be coated using methods well known in the art.

[0207] Other formulations suitable for oral administration include tablets containing a flavoring matrix, typically sucrose and active agents in gum arabic or astragalus gum; soft tablets containing an inert matrix such as gelatin and glycerin, or sucrose and gum arabic, containing active agents in a suitable liquid carrier; and mouthwashes containing active agents in a suitable liquid carrier.

[0208] Other forms of administration include solutions or emulsions prepared from sterile or sterile solutions for intravenous, intra-arterial, intrathecal, subcutaneous, intradermal, intraperitoneal, or intramuscular injection. Injectable formulations typically contain 10-1000 mg, preferably 10-250 mg, of the active ingredient per dose.

[0209] The administration method can also be combination administration, that is, combining one or more compounds of the present invention with one or more other active agents. In this case, the compounds of the present invention and one or more other active agents can be administered continuously, simultaneously, or sequentially. Detailed Implementation

[0440] Example 19: Preparation of ketoxime compounds

[0441]

[0442] General procedure: Under argon protection, 0.16 mmol of cinquercetin catalyst and 0.8 mmol of m-nitrobenzoic acid were added to a 4 mmol acetone (5 mL) solution of α-keto ester at room temperature. After reacting for 8 h, most of the solvent was removed and the mixture was separated by column chromatography to obtain the ketone analog.

[0443] At room temperature, the ketone compound (2 mmol) was dissolved in CH3CN / H2O (v / v = 9:1, 5 mL), and hydroxylamine hydrochloride (2 mmol) and sodium acetate (2.5 mmol) were added with stirring. After the reaction was complete as monitored by TLC, saturated NaHCO3 was added to quench the reaction, followed by extraction with CH2Cl2. The organic phases were combined, washed with saturated NaCl, and dried over anhydrous Na2SO4. The solvent was removed by rotary evaporation to obtain the E / Z ketoxime analog.

[0444] Following the method described above, the following compounds were obtained:

[0467] Example 20: Preparation of Aldoxime Compounds

[0468]

[0469] General procedure: Under argon protection, at -60°C, thioenol silyl ether (2 mmol) was added dropwise to a CH2Cl2 (15 mL) solution of α-keto ester (1 mmol). After 10 min, BF3·OEt2 (3 mmol) was added dropwise. After the reaction was monitored by TLC plate until complete, saturated NaHCO3 was added to quench the reaction, followed by extraction with CH2Cl2. The organic phases were combined, washed with saturated NaCl, and dried over anhydrous Na2SO4. The solvent was removed by rotary evaporation to obtain the thioester intermediate.

[0470] At room temperature, Pd / C (0.1 mmol) and Et3SiH (2.5 mmol) were added to a 5 mL CH2Cl2 solution of the thioester, and the reaction was monitored until complete. The mixture was quenched with saturated NaHCO3, filtered through diatomaceous earth, extracted with CH2Cl2, and the organic phases were combined, washed with saturated NaCl, and dried over anhydrous Na2SO4. The solvent was removed by rotary evaporation to obtain the aldehyde analog.

[0471] At room temperature, the intermediate aldehyde (2 mmol) was dissolved in CH3CN / H2O (v / v = 9:1, 5 mL), and hydroxylamine hydrochloride (2 mmol) and sodium acetate (2.5 mmol) were added with stirring. The reaction was monitored by TLC until complete. The reaction was quenched with saturated NaHCO3, extracted with CH2Cl2, and the organic phases were combined, washed with saturated NaCl, and dried over anhydrous Na2SO4. The solvent was removed by rotary evaporation to give the E / Z aldoxime analog.

[0472] Following the method described above, the following compounds were obtained:

[0508] Example 21: Preparation of oxime ester compounds

[0509]

[0510] General procedure: Under Ar atmosphere, at 0°C, Et3N (3 mmol) was added dropwise to a CH2Cl2 (5 mL) solution of oxime (1 mmol), followed by acetic anhydride (1.2 mmol). After the addition was complete, the solution was moved to room temperature, and the reaction was monitored by TLC until complete. The reaction was quenched with saturated NaHCO3, extracted with CH2Cl2, and the organic phases were combined. The mixture was washed with saturated NaCl and dried over anhydrous Na2SO4. The solvent was removed by rotary evaporation to obtain the crude oxime acetate product.

[0542] Example 23: Preparation of oxime ester compounds

[0543]

[0544] General procedure: Under Ar atmosphere, add dropwise naproxen (1 mmol), EDCI (1.1 mmol), and DMAP (0.2 mmol) in CH2Cl2 (2 mL) to a 1 mmol CH2Cl2 solution of oxime. Monitor the reaction on a TLC plate until complete. Quench with saturated NaHCO3, extract with CH2Cl2, combine the organic phases, wash with saturated NaCl, and dry with anhydrous Na2SO4. Remove the solvent by rotary evaporation to obtain the crude oxime ester product.
