摘要:
A process for producing an optically active benzopyran compound of the formula [I] or [II]: ##STR1## in which an olefin compound of the formula [V] or [VI]: ##STR2## is subjected to asymmetric epoxidation reaction, using, as a catalyst, an optically active manganese complex of the formula [III] or [IV]: ##STR3##
