摘要：

Variously substituted O-ethyl S-(2-azido-2-deoxy-D-galactopyranosyl) dithiocarbonates have been easily prepared via a two-step azidoxanthation reaction of the corresponding galactals (1,5-anhydro-2-deoxy-D-lyxo-hex-1-enitols). They are efficient glycosyl donors for the stereoselective synthesis of protected precursors of biologically important galactosamine-containing oligosaccharides.
