Definitions
- the present invention relates to a method for producing an optically active sulfoxide derivative having an anti-ulcer effect.
- An optically active sulfoxide derivative having an anti-ulcer action can be obtained by asymmetric oxidation of a prochiral sulfide derivative.
- sulfone which is an excess reactant, is generated. Therefore, the resulting sulfoxide derivative includes, as analogs, an unreacted sulfide derivative and an excess reactant, a sulfone derivative.
- WO 96/02535 Japanese Patent Application Laid-Open No. 10-504290 discloses that a sulfide derivative is oxidized in an organic solvent in the presence of a chiral titanium complex and a base.
- a method for obtaining an optically active sulfoxide compound by reacting the compound with an agent is described.
- 2 _ [[[3-methyl-4- (2,2,2.2-trifluoroethoxy) -12-pyridinyl] methyl] thio] -1H-benzimidazole (6 2.0 mmol) in water (3.6 mmol),
- 2000-16992 discloses that a specific thioether compound is oxidized with N-halosuccinimide, 1,3-dihalo 5,5-dimethylhydantoin or dichloroisocyanurate in the presence of a base. It describes a method for obtaining a sulfoxide compound. Also, depending on the reaction conditions, there is a problem that the reaction does not stop at the sulfoxide, and a side reaction occurs in which a part of the generated sulfoxide is further oxidized to a sulfone. It also describes that the yield is low, and there are problems that separation and purification are difficult because the physicochemical properties of both are very similar.
- the desired optically active sulfoxide has low optical purity (enantiomeric excess), which produces a difficult-to-remove sulfone, so purification by column chromatography is indispensable and the yield is high. There was a problem that it was low. Therefore, there is a demand for a process for producing an optically active sulfoxide derivative having an antiulcer activity, which is industrially advantageous in terms of the amount of related substances, optical purity, yield, productivity and economy. Disclosure of the invention,
- the amount of the oxidizing agent used is reduced in order to suppress the excess reaction, that is, the formation of the sulfone derivative.
- the amount of the oxidizing agent used relative to the raw material is 0.9 to 1.1 molar equivalents.
- the abundance of the sulfone derivative is 1.2 to 8.8%.
- the present inventors have studied various methods for producing an optically active sulfoxide derivative. Unexpectedly, if the oxidation reaction is carried out at a temperature lower than room temperature by using an excess of acid acid, the sulfone derivative is obtained. For the first time, found that an optically active sulfoxide derivative with extremely low optical purity and extremely low optical purity can be produced at a high yield. Researched and completed the present invention.
