ALTERNATIVE SYNTHESES AND RELATED N.M.R. STUDIES OF PRECURSORS FOR INTERNAL β-D-GALACTOPYRANOSYL RESIDUES IN OLIGOSACCHARIDES, ALLOWING CHAIN EXTENSION AT O-4

Crystalline 2,3,6-tri-O-benzoyl-4-O-(bromoacetyl)-α-D-galactopyranosyl chloride (5) was prepared from methyl 2,3,6-tri-O-benzoyl-4-O-(bromoacetyl)-α- or -β-D-galactopyranoside by cleavage with dichloromethyl methyl ether (DCMME) in the presence of zinc ch
