英文摘要: The asymmetric cyclopropanation of styrene with alkyl diazoacetate were performed with copper complexes of Schiff bases, derived from substituted salicylaldehydes and a new chiral amino alcohol, as the catalysts. The electronic and steric properties, as well as the position of those substituents show obvious effects on the enantioselectivities, and ee higher than 98% were achieved under optimal conditions.
