摘要：

A strategy for the preparation of a supported 'salen-type Mn(III) catalyst derived from D-glucose is described. The, compound has been prepared by introducing the ligand functions at positions 2 and 3 of the sugar, which has been subsequently anchored to a CHO-modified Wang resin through formation of a 4,6-O-benzylidene ring. The activity of the catalyst in the asymmetric epoxidation of styrenes has been investigated by using four different oxidants. (C) 2005 Elsevier B.V. All rights reserved.
