Abstract Benzyl 2-acetamido-2-deoxy-3-O-methyl-α-d-glucopyranoside (3) was obtained by deacetalation of its 4, 6-O-benzylidene derivative (2). Compound 2 was prepared by methylation of benzyl 2-acetamido-4, 6-O-benzylidene-2-deoxy-α-d-glucopyranoside with methyl iodide-silver oxide in N, N-dimethylformamide. Diol 3 was selectively benzoylated and p-toluenesulfonylated, to give the 6-benzoic and 6-p-toluenesulfonic esters (4 and 5, ...
