O-Dichlorovinyl Osides: A New Anomeric Protecting Group

Abstract

Dichlorovinyl glycopyranosides are obtained from peracetylated glycopyranoses by a Wittig-type reaction with Ph₃P/CCl₄ on anomeric acetate. This new type of glycosides has been used to get rapid access to the corresponding perbenzylated glycopyranoses.

Key words

glycosides - Wittig-type reactions - regioselectivity - microwave irradiation
