英文摘要	asymmetric cyclopropanation of olefins was carried out with chiral copper-schiff base complexes derived from copper acetate monohydrate, substituted salicylaldehydes and a chiral amino alcohol. substituents on salicylaldehyde framework demonstrate a significant effect on the steroselectivities. those with electron-withdrawing properties enhance the selectivities, whereas bulky sustituents in ortho position to the phenol hydroxy group decrease the selectivities. an ee of more than 98% was achieved for the reaction of styrene with diazoacetate.
