ABSTRACT:
There is provided a novel method for producing an optically active succinimide compound which is a useful compound utilized as an intermediate raw material for pharmaceutical products or the like. The method for producing an optically active succinimide compound of formula (2) comprises processing a racemic compound of a succinimide compound of formula (1) in the presence of a hydrolase to selectively hydrolyze one of the enantiomers, and subjecting to a post-treatment.
