Abstract
Abstract 2-acetamido-2-deoxy-4- O -β- D -galactopyranosyl- D -mannose (6) and - D -glucose (7) were prepared by addition of nitromethane to 3- O -β- D -galactopyranosyl- D -arabinose, followed by acetylation, ammonolysis, and application of the Nef reaction. Similarly, 2-acetamido-2-deoxy-4- O -β- D -mannopyranosyl- D -mannose (14) and - D -glucose (15) were prepared by the same scheme from 3- O -β- D -mannopyranosyl- D -arabinose. In the two series of experiments, 6 and 14 were the respective major products. Epimerization of the 2-acetamido-2-deoxy- D -mannose residue in 6 and 14 yielded 7 and 15, respectively.
