摘要：

Allylic alcohols are epoxidized with tert-butyl hydroperoxide in the presence of a vanadyl salen ore-transfer catalyst in supercritical CO2 The metal catalyst was prepared in a simple two.step, Schiff base reaction to form the salen ligand, followed by complexation to the vanadyl group. The epoxidation reactions are clean and give both high yields and good diastereoselectivity. (C) 1998 Elsevier Science Ltd. All rights reserved.
