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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
