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. © 1991.

Abstract
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. © 1991.File in questo prodotto:
