Regioselective One-Pot Protection of<scp>d</scp>-Glucosamine

Abstract

A highly regioselective one-pot transformation of 2-azido-2-deoxy-1,3,4,6-tetra-O-trimethylsilyl-d-glucopyranose via sequential additions of various reagents was systematically studied, yielding the fully protected derivatives and the 1-, 3-, 4-, as well as 6-alcohols, respectively.
