D-Glucose, D-galactose, D-mannose, D-xylose, L-arabinose, L-fucose, L-rhamnose, maltose, cellobiose, lactose, D-glucosamine, D-galactosamine, and D-mannosamine were converted into the corresponding methyl per-<I>O</I>-acetyl 1-thioglycopyranosides by way of a three-step (acetobromination, methylthioation, and acetylation) through-process in a single vessel.
