Reaction Steps

A mixture of benzyl (2-{[α-D-mannopyranosyl-(1→3)-[α-D-mannopyranosyl-(1→6)]-4-O-benzyl-β-D-glucopyranosyl]oxy}ethyl)carbamate (0.96 g, 1.244 mmol) and Pd/C (124 mmol) in water (20 mL) was allowed to stir under a balloon of H2 at rt for 16 h. The catalyst was filtered off and washed with H2O (3×10 mL). The Titrate was concentrated to give the title compound. UPLC Method B: calculated for C20H37NO16 547.21, observed m/e: 548.29 [M+1]; Rt=0.87 min. 1H NMR (D2O) δ 5.20-5.19 (1H, m), 4.88-4.87 (1H, m), 4.51-4.49 (1H, m), 4.05 (1H, m), 4.00-3.90 (4H, m), 3.85-3.70 (9H, m), 3.70-3.60 (5H, m), 3.40-3.30 (1H, m), 3.05-3.00 (2H, m).
