An efficient and high yielding reaction for tandem opening of 4,6-O-benzylidene derivatives (gluco, galacto, manno, 2-phthalimido-2-deoxy glucosides) to their corresponding 6-O-acetyl derivatives has been established under metal free condition using 60% solution of aqueous acetic acid (v/v). The reaction is equally pertinent for large scale synthesis and also for disaccharide glycosides. Its application for the construction of a building block towards synthesis of a trisaccharide part related to Pseudomonas aeruginosa utilizing one-pot glycosylation reactions has also been described.

The effect of conformation on glycoside reactivity was investigated by studying the hydrolysis of a selection of 3,6-anhydroglucosides as models for glucose in the highly reactive 1C4 conformation. Methyl 3,6-anhydro-β-D-glucopyranoside was found to hydrolyze 200-400 times faster than methyl glucosides in the 4C1 conformation, while methyl 3,6-anhydro-β-D-galactopyranoside, which is in the B1,4 conformation, was less reactive than methyl β-D-galactopyranoside. Methyl (3,6-anhydro-β-D-glucopyranosyl)-(1 → 6)-α-D-glucopyranoside, methyl (3,6-anhydro-α-D-glucopyranosyl)-(1 → 6)-α-D- glucopyranosyl-(1 → 6)-α-D-glucopyranoside, and methyl (3,6-anhydro-β-D-glucopyranosyl)-(1 → 6)-α-D-glucopyranosyl-(1 → 6)-α-D-glucopyranoside were prepared and found to react selectively at the anhydro residue. The finding that 1C4 conformers of glucosides are highly reactive species is in accordance with and supports previous results showing that axial OH groups are less electron withdrawing than equatorial OH groups.
