Corrected order in the simultaneous debenzylation–acetolysis of methyl 2,3,4,6-tetra-O-benzyl-α-d-glucopyranoside

The benzyl groups of methyl 2,3,4,6-tetra-O-benzyl-α-d-glucopyranoside were cleaved in the order of 6-O-Bn > 3-O-Bn > 4-O-Bn > 2-O-Bn under acid-mediated conditions in acetic anhydride. The order is a correction of that previously reported.
