In a continuing program for the synthesis of oligosaccharides that occur as part of mutinous glycoconjugates, we previously described\* the synthesis of the disaccharide methyl 3-0-(2-acetamido-2-deoxy-P-D-glucopyranosyl)-a-D-galactopyranoside (1). We have also demonstrated that 1 could be readily
Condensation of benzyl 2-acetamido-4,6-O-benzylidene-2-deoxy-a-D-galactopyranoside with 2,3,4-tri-o-acetyl-a-D-fucopyranosyl bromide in 1: 1 nitromethane-benzene, in the presence of powdered mercuric cyanide, afforded benzyl 2-acetamido-4,6-O-benzylidene-2-deoxy-3-0-(2,3,4-tri-O-acetyl-P-D-fucopyran
