Herein we describe a simple and practical methodology for accessing both the α-anomers (d-mannose, N-acetyl-d-glucosamine, N-acetyl-d-galactosamine, d-lactose) and α- and β-anomers (d-glucose, d-galactose, l-fucose) of 2′-azidoethyl and azidotriethylene glycol glycosides using free sugars and Dowex 50 (resin) as an efficient catalyst. These azidoalkyl glycosides are increasingly useful synthetic intermediates for glycotechnology.
