AI Technical Summary
Current methods for the regioselective and stereoselective synthesis of 3-substituted alkenes face challenges due to the limited availability of starting compounds, particularly 3-substituted vinyl (pseudo)halides, and issues with regioselectivity and stereoselectivity in cross-coupling reactions.
The development of a 3-substituted vinylsulfoximine derivative represented by formula (I) or its salts, which serves as a precursor for the regioselective and stereoselective synthesis of trisubstituted alkenes, utilizing a cross-coupling reaction with a palladium catalyst and a ligand to control the stereochemistry of the produced alkene.
The method allows for the simple and stereoselective synthesis of trisubstituted alkenes, maintaining the stereochemistry of the compound used, and provides a versatile precursor for regioselective synthesis.

Abstract
Description
Technical Field
[0001] The present invention relates to a novel 3-substituted vinylsulfoximine derivative or a salt thereof, which is a precursor useful for the regioselective and stereoselective synthesis of 3-substituted alkenes, a method for producing the same, and a method for producing a stereoselective 3-substituted alkene using the same.
Background Art
[0002] 3-Substituted alkenes are structures contained in many pharmaceuticals and organic functional molecules. However, for 3-substituted alkenes with different substituents, regioselective and stereoselective synthesis is difficult, and there is currently no highly versatile synthesis method.
[0003] As a synthesis method for 3-substituted alkenes, the cross-coupling reaction is one of the effective methods. However, the biggest problem is that it is not easy to obtain the starting compound, 3-substituted vinyl (pseudo) halides, and there are limitations on the starting compounds that can be used.
[0004] The known synthesis methods for 3-substituted vinyl (pseudo) halides are specifically classified into four types: (a) a conversion reaction from a classical carbonyl group (Shapiro reaction), (b) a conversion reaction by cross-coupling from 1,1-dihalides (for example, Non-Patent Document 1), (c) a conversion reaction by addition to an alkyne (hydrohalogenation reaction) (for example, Non-Patent Documents 2 and 3), and (d) a conversion reaction by olefin metathesis (cross-metathesis) (for example, Non-Patent Documents 4 and 5).
[0005] However, in any of the above synthesis methods, there are problems in either the regioselectivity and / or stereoselectivity of the obtained 3-substituted alkene, or the availability of reaction reagents, catalysts, and starting compounds. Therefore, it is difficult to call them universal synthesis methods.
[0006] On the other hand, Non-Patent Document 6 discloses the following formula:
[0007]
Chemical Formula
[0008] (The definitions of the symbols in the formula are as described in Non-Patent Document 6.) Examples have been reported in which a cross-coupling reaction using a specific 3-substituted vinylsulfoximine represented by the formula as a pseudo-halide is used to convert it to a 3-substituted alkene. However, in Non-Patent Document 6, the reaction substrates are limited, and since it is difficult to obtain other 3-substituted vinylsulfoximines, this finding has not been directly utilized for the synthesis of other 3-substituted alkenes thereafter.
[0009] In fact, although several synthesis examples of 2-substituted vinylsulfoximines in which the α-position is a hydrogen atom are known (Non-Patent Documents 7 to 10), as synthesis examples of 3-substituted vinylsulfoximines, almost none are known other than the specific compounds described in Non-Patent Document 6.

[0101] (Method for producing the compound of the present invention (compound (I))) Hereinafter, a method for producing the compound (I) or a salt thereof (hereinafter, also referred to as "method for producing the compound (I)") will be described. As an example of the method for producing the compound (I), typical production methods are described below, but the production method is not limited thereto. The compound (I) can be produced by the following production methods, Examples 1 to 8 described later, or methods analogous thereto.
[0102] The starting compounds, reagents, and the obtained compounds used in the steps in the following production methods may each form a salt. Examples of such salts include the same salts as those described above. When the obtained compound (I) is a free compound, it can be converted into the desired salt by a known method. Conversely, when the obtained compound (I) is a salt, it can be converted into the free form or another desired type of salt by a known method.
[0103] In this specification, the content of all non-patent documents or references explicitly cited can all be cited here as part of this specification.
[0104] [Production Method] (Step 1) The production method of compound (I) is a method of obtaining compound (I) by subjecting compound (1) described in the following scheme as a starting material to a reaction with compound (2) in the presence of a base.
[0105] [Chemical Formula]
[0106] (Each symbol in the formula has the same meaning as described above.)
[0107] This step is a step of producing compound (I) (compound (I) in which R is a hydrogen atom) by reacting compound (1) with compound (2) in a solvent in the presence of a base.
[0108] The solvent to be used is not particularly limited as long as it does not affect the reaction, but preferably, for example, aromatic hydrocarbons such as benzene, toluene, xylene, etc.; ethers such as diethyl ether, tetrahydrofuran, 1,4-dioxane, 1,2-dimethoxyethane, etc.; amides such as N,N-dimethylformamide; mixed solvents containing a plurality of the above organic solvents in an arbitrary ratio, etc. are mentioned, and preferably, it is N,N-dimethylformamide.
[0109] The bases to be used are not particularly limited. For example, organic bases such as 1,8-diazabicyclo[5.4.0]-7-undecene; alkali metal carbonates such as sodium carbonate, potassium carbonate, cesium carbonate; alkaline earth metal carbonates such as magnesium carbonate; alkali metal hydroxides such as sodium hydroxide; alkaline earth metal hydroxides such as magnesium hydroxide; metal alkoxides such as sodium tert-butoxide, potassium tert-butoxide; metal amides such as lithium diisopropylamide, sodium hexamethyldisilazide; organometallic compounds such as tert-butyllithium; metal hydrides such as potassium hydride, sodium hydride, etc. Among them, preferably, sodium hydride or potassium hydride is used. The amount of the base used is usually 1.5 to 3 moles, preferably 2 moles, per 1 mole of compound (1).
[0110] Compound (1) can be prepared from commercially available products (sulfides or sulfoxides) by the methods described in the reference examples below, methods known per se (for example, see Chem. Commun., 2017, 53, 348 - 351; Org. Lett., 2023, 25, 7529 - 7534; Angew. Chem. Int. Ed., 2016, 55, 7203 - 7207, etc.), or by methods analogous thereto. Specifically, for example, in the presence of ammonium carbamate, sulfides are reacted with iodobenzene diacetate, converted to the corresponding sulfoximine, and then a protecting group (PG) is introduced onto the nitrogen atom to produce compound (1).
[0111] Compound (2) can be preferably used as a commercially available product as it is or synthesized by a method known per se. The amount of compound (2) used is usually 1.5 to 3 moles, preferably 2 moles, per 1 mole of compound (1).
[0112] The reaction temperature is usually 0°C to 60°C, preferably room temperature (15°C to 30°C).
[0113] The reaction time is usually 1 to 8 hours, preferably 2 to 4 hours.
[0114] In the production method of the present invention, since the sulfoximino group is a bulky group, after the condensation of compound (1) and compound (2), the protecting group (PG) on the nitrogen atom has the following formula:
[0115]
Chemical formula
[0116] (In the formula, R 0 represents a C 1-6 alkyl group, a C 6-14 aryl group or an aromatic heterocyclic group, and the other symbols have the same meanings as described above.) Since it is presumed that the elimination reaction from the 1,5-carbonyl transfer via the intermediate represented by proceeds, the resulting compound (I) selectively forms almost only the E-isomer (E / Z => 99:1).
[0117] On the other hand, when the protecting group (PG) on the nitrogen atom is a group other than the -C(=O)R 0 (that is, a C 1-6 alkyl-carbonyl group, a C 6-14 aryl-carbonyl group or an aromatic heterocyclic-carbonyl group which may be each substituted with one or more substituents selected from the above-mentioned substituent group a), for example, when PG is a hydrogen atom or a methyl group, or when the =N-PG group in formula (1) is =O), the reaction in this step does not proceed.
[0118] (Step 2) For the compound (I) in which R in the formula (I) is a C 1-6 alkyl group, the compound (I) obtained in the above step 1 (the compound in which R in formula (I) is a hydrogen atom) is reacted with a compound of the formula:
[0119]
Chemical formula
[0120] (In the formula, X represents a halogen atom, and R represents a C 1-6 alkyl group.) It can be produced by reacting a compound represented by
[0121] The amount of R-X used is usually 1 to 3 moles, preferably 1.1 to 1.5 moles, per 1 mole of compound (I) (a compound in which R in formula (I) is a hydrogen atom).
[0122] Examples of the solvent used include the same solvents as in Step 1 above, and preferably tetrahydrofuran.
[0123] Examples of the base used include the same bases as in Step 1 above, and among them, preferably sodium hydride or potassium hydride. The amount of the base used is usually 1 to 3 moles, preferably 1.1 to 1.5 moles, per 1 mole of compound (I) (a compound in which R in formula (I) is a hydrogen atom).
[0124] The compound (I) obtained by the above production method can be isolated and purified by known means, such as solvent extraction, liquid conversion, phase transfer, crystallization, recrystallization, chromatography, etc.
[0125] When compound (I) contains optical isomers, stereoisomers, positional isomers, or rotational isomers, these are also contained as compound (I), and each can be obtained as a single product by synthetic methods and separation methods known per se. For example, when optical isomers exist in compound (I), the optical isomers separated from the compound are also included in compound (I).
[0126] (Method for producing a stereoselective 3-substituted alkene using the compound (compound (I)) of the present invention) Hereinafter, the conversion reaction of compound (I) or a salt thereof to 3-substituted alkene (compound (II)) will be described.
[0127] This process can be carried out by a cross-coupling reaction (Suzuki-Miyaura cross-coupling reaction) between compound (I) and compound (3) in a solvent that does not affect the reaction, in the presence of a palladium catalyst and a ligand.
[0128] [Chemical formula]
[0129] (In the formula, R represents a C 1-6 alkyl group, and each of the other symbols has the same meaning as described above.)
[0130] Compound (I) can be produced by the above production method (production method of compound (I)) or a method analogous thereto. As compound (3), a commercially available product can be used, or it can be produced by a method known per se [for example, the methods described in "Advanced Organic Chemistry, 4th Ed." (written by Jerry March), "Comprehensive Organic Transformations, 2nd Ed." (written by Richard C. Larock)] or methods analogous thereto. It can be produced.
