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. O-(2-Acetamido-2-deoxy-β-D-glucopyranosyl)-(1 → 4)-O-α-D-mannopyranosyl- (1 → 4)-a-D-mannopyranose, the repeating unit of the main chain of the O- specific cell wall polysaccharide of E. coli 058 was synthesized.
Di and Tri saccharides, methods of making them and hair growth compositions containing them

, (2008/06/13)
The preparation of a di or tri saccharide in which at least one glycoside residue bears an acetylamino substituent is catalysed enzymatically using an impure enzyme preparation with N-acetylhexosaminidase activity. The compounds produced, some of which are novel, may be useful to stimulate hair growth.
