摘要：

A large set of copper complexes, prepared in situ from copper(I)-triflate and a variety enantiopure oxazoline ligands, was assessed as chiral catalysts in the enantioselective cyclopropanation of styrene by ethyl diazoacetate. Enantioselectivities up to 60% and up to 52%, respectively, for trans- and cis-2-phenylcyclopropanecarboxylate were observed. (C) 2000 Elsevier Science Ltd. All rights reserved.
