Facile Preparation of 3,4-Di-O-acetyl-1,6-anhydro-2-azido-2-deoxy-β-D-glucopyranose and Some Derivatives Thereof: Useful Precursors for Oligosaccharide Synthesis

A facile, virtually one-pot synthesis of the title compound and also some of its derivatives is based on regioselective 2-substitutions of 1,6-anhydro-β-D-mannopyranose using stannylidene activation.The compounds thus prepared are useful precursors in the synthesis of glycoprotein-type oligosaccharides.

SYNTHESIS AND CHARACTERIZATION OF METHYL 6-O-β-D-GALACTOPYRANOSYL-β-D-GALACTOPYRANOSIDE AND METHYL O-β-D-GALACTOPYRANOSYL-(16)-O-β-D-GALACTOPYRANOSYL-(16)-β-D-GALACTOPYRANOSIDE

6-O-Acetyl-2-O-benzoyl-3,4-di-O-benzyl-α-D-galactopyranosyl chloride (8) was prepared from 1,6-anhydro-2-O-benzoyl-3,4-di-O-benzyl-β-D-galactopyranose via the corresponding 1,6-di-O-acetyl derivative 7.The glycosyl chloride 8 was converted into the 1-O-to
