Patent ID: 7754899

Claim:
A method for producing an optically active aziridine compound represented by the following formula (V), which comprises using as a catalyst an optically active Ru(salen)(CO) complex represented by the following formula (I) or (II); and subjecting an olefin represented by the following formula (III) to an asymmetric aziridination with a sulfonyl azide compound represented by the following formula (IV): in the formulae (I) and (II), Ar is represented by the following formula (VI) or (VII): , in the formula (VI), Xs are independently a halogen or a halogenated alkyl group, and R 1 and R 2 s are independently a hydrogen or an alkyl group or a trialkylsilyl group having a carbon number of 1 to 4, and in the formula (VII), R 3 is a group formed by bonding three alkyl groups or aryl groups to carbon or silicon; wherein R 4 is an alkyl group or a substituted alkyl group having a carbon number of 1 to 15, an alkenyl group or a substituted alkenyl group having a carbon number of 2 to 20, an alkynyl group or a substituted alkynyl group having a carbon number of 2 to 20, or an aryl group or a substituted aryl group having a carbon number of 6 to 20, R 5 is a hydrogen, or an alkyl group or a substituted alkyl group having a carbon number of 1 to 10, with the proviso that R 4 and R 5 may be bonded with each other to form a ring; R 6 —SO 2 N 3 (IV) wherein R 6 is an alkyl group, a substituted alkyl group, an aryl group or a substituted aryl group; wherein each of R 4 , R 5 and R 6 is the same meaning as mentioned above.
