DISACCHARIDES

A disaccharide having the structure (Formula I), and a disaccharide having the structure (Formula II) exhibit immunomodulatory activity.

Glycosylation using 2-azido-3,4,6-tri-O-benzyl-2-deoxy-D-glucose, - galactose, and -mannose with the aid of p-nitrobenzenesulfonyl chloride- silver trifluoromethanesulfonate-triethylamine system

This report describes a simple synthesis of 2-azido-3,4,6-tri-O-benzyl- 2-deoxy-D-glucopyranose. Glycosylation using this as well as 2-azido-3,4,6- tri-O-benzyl-2-deoxy-D-galactopyranose and -mannopyranose was achieved with the aid of a reagent system consisting of p-nitrobenzenesulfonyl chloride, silver trifluoromethanesulfonate, and triethylamine, and its modifications.
