A simple access to 3,6-branched oligosaccharides: Synthesis of a glycopeptide derivative that relates to Lycium barbarum L.

Abstract

An efficient method is described for the synthesis of galactopyranosyl-containing 3,6-branched oligosaccharides using isopropyl thiogalactopyranoside as starting material. This method is successfully applied to the preparation of a glycopeptide derivative that relates to Lycium barbarum L. The potential application of isopropyl thioglycoside in glycosylation is also investigated.
