ABSTRACT:
This invention provides a method for producing an optically active aziridine compound or amine compound, which uses as a catalyst a Ru(salen)(CO) complex represented by the following formula (I) or its enantiomer having a high stability, in a high turnover number (TON) and a high enantioselectivity. In the formula (I), Ar is represented by the following formula (VI) or (VII), wherein in the formula (VI), Xs are independently a halogen or a halogenated alkyl group and R1and R2s are independently hydrogen or an alkyl group or a trialkylsilyl group having a carbon number of 1-4, and in the formula (VII), R3is a bulky group.
