Patent ID: 7994342

Claim:
A method for producing an optically active succinimide compound represented by formula (2): (where * represents an asymmetric carbon atom; and R 1 , R 2 , R 3 and R 4 represent the same as defined in formula (1)), the method comprising: processing a racemic compound of a succinimide compound represented by the formula (1): (where R 1 represents an alkyl group having 1 to 12 carbon atoms which may be a straight chain, branched or cyclic, or an aromatic group having 6 to 12 carbon atoms which may be substituted; R 2 and R 3 independently represent a hydrogen atom, an alkyl group having 1 to 12 carbon atoms which may be a straight chain, branched or cyclic, an acyl group having 2 to 6 carbon atoms which may be substituted, an alkoxycarbonyl group having 1 to 6 carbon atoms which may be substituted, a benzyl group of which an aromatic ring part may be substituted or a benzyloxycarbonyl group of which an aromatic ring part may be substituted, or R 2 and R 3 together with a nitrogen atom to which R 2 and R 3 are bonded can form a ring; and R 4 represents a hydrogen atom, an alkyl group having 1 to 12 carbon atoms which may be a straight chain, branched or cyclic, or an aromatic group having 6 to 12 carbon atoms which may be substituted), in the presence of a hydrolase to selectively hydrolyze one of the enantiomers; and subjecting to a post-treatment.
