| titleOfInvention | Method for producing optically active acylsulfonamides |
| abstract | (57) Abstract: A process for producing an acylsulfonamide derivative having an asymmetric carbon atom substituted with an oxy group at the α-position of a carbonyl group. SOLUTION: General formula (III) having an asymmetric carbon atom substituted by an oxy group at the α-position: To the optically active carboxylic acid represented by The reaction is carried out in an inert solvent at −30 ° C. to room temperature in an inert solvent to obtain a compound of the general formula (II): After the acid chloride represented by the general formula (I) V): embedded image Is reacted in an inert solvent in the presence of 2 to 8 equivalents of an inorganic base, or 1 to 2 equivalents of a compound represented by the formula (IV): Reacting .about.2 equivalents in an inert solvent in the absence of a base, characterized by the general formula (I): A process for producing acylsulfonamides having an optical purity of 95% or more, represented by the formula: |
