ABSTRACT:
Treatment of a lactic acid ester derivative with an enzyme or the like, which has asymmetric ester-hydrolyzing ability, can specifically hydrolyze the ester moiety of an isomer existing as the pair to the racemic derivative. Use of the compound obtained by this hydrolysis makes it possible to produce an optically active propoxyaniline derivative by a shorter process than the conventional art
