Abstract

Cyclopropanation of styrene derivatives with alkyl alpha -diazoacetate in the presence of the second-generation (salen)cobalt(II) complex 6 proceededwith excellent cis- and enantioselectivity. On the other hand, the cyclopropanation in the presence of complex 14 which was designed on the basis of the mechanism of asymmetric induction by complex 6 showed good trans- and excellent enantioselectivity.
