[0008] The present disclosure relates to a series of compounds containing hexahydrospiro[cyclopropane-1,2'-pyrrolizine], and specifically to compounds represented by formula (III), stereoisomers thereof, and pharmaceutically acceptable salts thereof. Background Art

[0009] KRAS is a member of the ubiquitously expressed RAS protein family (KRAS, NRAS, and HRAS). It regulates the transduction of extracellular signals to downstream intracellular pathways by binding to GTP (on) or GDP (off). However, mutations in this protein often impair its GTP hydrolase activity, leading to prolonged activation and overactivation of downstream molecules, thus promoting abnormal cell proliferation and cancerous transformation. Due to the shallow GTP binding pocket in the KRAS protein, which is abundant in cells, effective KRAS-targeted inhibitors have remained elusive despite over three decades of research, leading to the KRAS gene being termed "undruggable." The sluggish progress in targeted therapy for KRAS mutations has resulted in patients with KRAS mutations remaining primarily treated with traditional chemotherapy and radiotherapy, depriving them of the benefits of modern precision medicine. In recent years, advances in drug discovery and the emergence of novel approaches have led to the successful development of covalent inhibitors for the KRAS G12C mutation, rekindling hopes for the development of inhibitors that directly target KRAS. The most common KRAS mutations occur at glycine 12 (G12), glycine 13 (G13), and glutamine 61 (Q61) residues, with G12 mutations accounting for 83%. G12D mutations are a relatively common subtype of KRAS mutations, which involve the conversion of glycine 12 (G) to aspartic acid (D). KRAS G12D mutations are most common in pancreatic cancer. According to data reported in the literature (Nat Rev Drug Discov 2014;13:828-851), approximately 46% of pancreatic cancers, 15% of colorectal cancers, and 5% of non-small cell lung cancers harbor KRAS G12D mutations.

[0010] As a cutting-edge target, the KRAS G12D mutant protein has yet to see any small molecule inhibitors enter clinical development, with only limited preclinical studies reported. In 2021, MIRATI THERAPEUTICS, INC. published a patent (WO2021041671) for a KRAS G12D small molecule inhibitor, which discloses a series of pyridopyrimidine compounds with high KRAS G12D activity.

[0192] Definition and Description

[0193] Unless otherwise indicated, the following terms and phrases used herein are intended to have the following meanings. A particular term or phrase should not be construed as indefinite or unclear unless specifically defined, but rather should be understood in accordance with its ordinary meaning. When a trade name appears in this document, it is intended to refer to the corresponding commercial product or its active ingredient.

[0194] The term "pharmaceutically acceptable" as used herein refers to those compounds, materials, compositions and / or dosage forms which, within the scope of sound medical judgment, are suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response or other problems or complications, commensurate with a reasonable benefit / risk ratio.

[0195] The term "pharmaceutically acceptable salt" refers to salts of the compounds of the present disclosure, which are prepared by reacting the compounds of the present disclosure with relatively nontoxic acids or bases. When the compounds of the present disclosure contain relatively acidic functional groups, base addition salts can be obtained by contacting the compounds with a sufficient amount of base in a neat solution or a suitable inert solvent. Pharmaceutically acceptable base addition salts include sodium, potassium, calcium, ammonium, organic amine or magnesium salts or similar salts. When the compounds of the present disclosure contain relatively basic functional groups, acid addition salts can be obtained by contacting the compounds with a sufficient amount of acid in a neat solution or a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include inorganic acid salts such as hydrochloric acid, hydrobromic acid, nitric acid, carbonic acid, bicarbonate, phosphoric acid, monohydrogen phosphate, dihydrogen phosphate, sulfuric acid, bisulfate, hydroiodic acid, phosphorous acid, and the like; and organic acid salts such as acetic acid, propionic acid, isobutyric acid, maleic acid, malonic acid, benzoic acid, succinic acid, suberic acid, fumaric acid, lactic acid, mandelic acid, phthalic acid, benzenesulfonic acid, p-toluenesulfonic acid, citric acid, tartaric acid, and methanesulfonic acid; and salts of amino acids such as arginine, and salts of organic acids such as glucuronic acid. Certain specific compounds of the present disclosure contain basic and acidic functional groups and can be converted into either base or acid addition salts.

[0196] The pharmaceutically acceptable salts of the present invention can be synthesized by conventional chemical methods from parent compounds containing acid radicals or bases. Generally, such salts are prepared by reacting the free acid or base form of these compounds with a stoichiometric amount of an appropriate base or acid in water or an organic solvent or a mixture of the two.

[0197] The word "comprise" or "comprises" and its English variations such as comprises or comprising should be understood as having an open and non-exclusive meaning, ie, "including but not limited to".

[0198] The term "substituted" means that a specific atom or group can be replaced by a specified other atom or group. For example, one, two, or three -CH2- in -CH2CH2CH2- can be replaced by O, S, or NH to obtain -O-CH2-CH2-, -O-CH2-, -CH2-O-CH2-, -CH2-O-, -CH2-CH2-O-, -O-, etc.

[0199] The term "optionally" or "optionally" means that the event or circumstance described subsequently may or may not occur, and the description includes both the occurrence of the event or circumstance and the non-occurrence of the event or circumstance. For example, an ethyl group is "optionally" substituted with a halogen, meaning that the ethyl group may be unsubstituted (CH2CH3), monosubstituted (such as CH2CH2F), polysubstituted (such as CHFCH2F, CH2CHF2, etc.), or fully substituted (CF2CF3). It will be understood by those skilled in the art that for any group containing one or more substituents, no substitution or substitution pattern that would be sterically impossible and / or incomposable to synthesize will be introduced.

[0200] As used herein, "the configuration is consistent with compound 3-3A" means that the compound has a configuration consistent with the hexahydrospiro[cyclopropane-1,2'-pyrrolizine] moiety in compound 3-3A. For example, "the configuration of compound 3 is consistent with compound 3-3A" means that the configuration of the hexahydrospiro[cyclopropane-1,2'-pyrrolizine] moiety in compound 3 is consistent with the configuration of the hexahydrospiro[cyclopropane-1,2'-pyrrolizine] moiety in compound 3.

[0201] The compounds of the present disclosure may exist in specific geometric or stereoisomeric forms. The present disclosure contemplates all such compounds, including cis- and trans-isomers, (-)- and (+)-enantiomers, (R)- and (S)-enantiomers, diastereomers, (D)-isomers, (L)-isomers, and racemic mixtures and other mixtures thereof, such as enantiomerically or diastereomerically enriched mixtures, all of which are within the scope of the present disclosure. Additional asymmetric carbon atoms may be present in substituents such as alkyl groups. All of these isomers and their mixtures are included within the scope of the present disclosure.

[0202] Unless otherwise indicated, the term "enantiomer" or "optical isomer" refers to stereoisomers that are mirror images of one another.

[0203] Unless otherwise indicated, the term "cis-trans isomers" or "geometric isomers" arises from the inability to rotate freely about double bonds or single bonds forming ring carbon atoms.

[0204] Unless otherwise indicated, the term "diastereomer" refers to stereoisomers that have two or more chiral centers and that are not mirror images of each other.

[0205] Unless otherwise indicated, "(+)" indicates dextrorotatory, "(-)" indicates levorotatory, and "(±)" indicates racemic.

[0206] Unless otherwise specified, use a solid wedge key. and dotted wedge key To indicate the absolute configuration of a stereocenter, use a straight solid bond and straight dashed key Indicate the relative configuration of stereocenters with a wavy line Indicates a wedge-shaped solid key or dotted wedge key Or use a wavy line Indicates a straight solid bond or straight dashed key

[0207] The compounds of the present disclosure containing asymmetric carbon atoms can be isolated in optically pure or racemic forms. Optically pure forms can be resolved from racemic mixtures or synthesized by using chiral starting materials or reagents.

[0208] The compounds and intermediates of the present disclosure may also exist in different tautomeric forms, and all such forms are included within the scope of the present disclosure. Unless otherwise indicated, the term "tautomer" or "tautomeric form" refers to different functional group isomers that are in dynamic equilibrium at room temperature and can quickly convert into each other. If tautomers are possible (such as in solution), chemical equilibrium of the tautomers can be achieved. For example, proton tautomers (also known as prototropic tautomers) include interconversions that occur through proton migration, such as keto-enol isomerization and imine-enamine isomerization. Valence tautomers include interconversions that occur through the reorganization of some bonding electrons. A specific example of keto-enol tautomerization is the interconversion between two tautomers of pentane-2,4-dione and 4-hydroxypent-3-ene-2-one.

[0209] The compounds of the present disclosure may have one or more atropisomers. Unless otherwise specified, atropisomers refer to optically active isomers resulting from the obstruction of free rotation between single bonds. The compounds of the present disclosure containing a chiral axis can be isolated in racemic form. When the energy barrier for free rotation between single bonds of the compounds of the present disclosure containing a chiral axis is sufficiently high, the atropisomers can be isolated in optically pure form.

[0210] Unless otherwise indicated, the terms "enriched in one isomer", "isomerically enriched", "enriched in one enantiomer" or "enantiomerically enriched" mean that the content of one isomer or enantiomer is less than 100%, and the content of that isomer or enantiomer is greater than or equal to 60%, or greater than or equal to 70%, or greater than or equal to 80%, or greater than or equal to 90%, or greater than or equal to 95%, or greater than or equal to 96%, or greater than or equal to 97%, or greater than or equal to 98%, or greater than or equal to 99%, or greater than or equal to 99.5%, or greater than or equal to 99.6%, or greater than or equal to 99.7%, or greater than or equal to 99.8%, or greater than or equal to 99.9%.

[0211] Unless otherwise indicated, the term "isomer excess" or "enantiomeric excess" refers to the difference between the relative percentages of two isomers or two enantiomers. For example, if the content of one isomer or enantiomer is 90% and the content of the other isomer or enantiomer is 10%, the isomer or enantiomeric excess (ee value) is 80%.

[0212] The compounds of the present disclosure may contain unnatural proportions of atomic isotopes at one or more of the atoms that constitute the compound. For example, the compounds may be labeled with radioactive isotopes, such as tritium ( 3 H), iodine-125( 125 I) or C-14( 14 C). For another example, deuterated drugs can be formed by replacing hydrogen with heavy hydrogen. The bond between deuterium and carbon is stronger than the bond between ordinary hydrogen and carbon. Compared with non-deuterated drugs, deuterated drugs have advantages such as reduced toxic side effects, increased drug stability, enhanced efficacy, and prolonged drug biological half-life. All isotopic variations of the compounds disclosed herein, whether radioactive or not, are included within the scope of this disclosure.

[0213] The present disclosure also includes isotopically labeled compounds of the present disclosure that are identical to those described herein, but where one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into the compounds of the present disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, iodine, and chlorine, such as 2 H. 3 H. 11 C. 13 C. 14 C. 13 N. 15 N. 15 O. 17 O. 18 O. 31 P. 32 P. 35 S. 18 F. 123I. 125 I and 36 Cl et al.

[0214] Certain isotopically labeled compounds of the present disclosure (e.g., 3 H and 14 C-labeled) can be used in compound and / or substrate tissue distribution assays. 3 H) and carbon-14 (i.e. 14 C) isotopes are particularly preferred due to their ease of preparation and detectability. Positron emitting isotopes, such as 15 O. 13 N. 11 C and 18 F can be used in positron emission tomography (PET) studies to determine substrate occupancy. Isotopically labeled compounds of the disclosure can generally be prepared by following procedures analogous to those disclosed in the Schemes and / or Examples below, by substituting an isotopically labeled reagent for a non-isotopically labeled reagent.

[0215] In addition, the use of heavier isotopes such as deuterium (i.e. 2 H)) substitution may offer certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and may therefore be preferred in certain circumstances, wherein deuterium substitution may be partial or complete, partial deuterium substitution meaning that at least one hydrogen is replaced by at least one deuterium.

[0216] When any variable (e.g., R) occurs more than once in a compound's composition or structure, its definition at each occurrence is independent. Thus, for example, if a group is substituted with 0-2 Rs, the group may be optionally substituted with up to two Rs, with each occurrence of R being an independent choice. Furthermore, combinations of substituents and / or their variants are permissible only if such combinations result in stable compounds.

[0217] When the number of a linking group is 0, such as -(CRR)0-, it means that the linking group is a single bond.

[0218] When one of the variables is selected from a single bond, it means that the two groups it connects are directly connected. For example, when L in ALZ represents a single bond, it means that the structure is actually AZ.

[0219] When the listed linking groups do not specify their connection direction, the connection direction is arbitrary. For example, in ALZ, the linking group L is -MW-, which means that the structure can be AMWZ or AWMZ.

[0220] Unless otherwise specified, when a group has one or more connectable sites, any one or more sites of the group can be connected to other groups through chemical bonds. When the chemical bond connection mode is non-positional and there are H atoms at the connectable sites, when the chemical bond is connected, the number of H atoms at the site will decrease accordingly with the number of connected chemical bonds, and become a group with a corresponding valence. The chemical bond connecting the site to other groups can be a straight solid bond. Straight dotted key or wavy lines For example, the straight solid bond in -OCH3 indicates that it is connected to other groups through the oxygen atom in the group; The straight dashed bond in the group indicates that the two ends of the nitrogen atom in the group are connected to other groups; The wavy line in the phenyl group indicates that it is connected to other groups through the carbon atoms at positions 1 and 2 in the phenyl group; Indicates that any linkable site on the piperidinyl group can be connected to other groups through a chemical bond, including at least In these four connection methods, even if an H atom is drawn on -N-, Still includes For groups connected in this way, when one chemical bond is connected, the H at that site will be reduced by one and become a corresponding monovalent piperidine group. It means that R can be connected to either end of the double bond, that is, When a substituent's bond crosses two atoms in a ring, the substituent may be bonded to any atom in the ring. It means that it can be substituted at any position on the cyclohexyl group or cyclohexadiene.
