Reaction Steps

To a solution of 1,2,3,4-tetra-O-acetyl-6-azido-6-deoxy-α-D-glucopyranose (IV, 850 mg, 2.78 mmol) in THF (12 mL) was added benzylamine (0.23 mL) and the mixture was stirred at rt overnight. Solvents were removed under the reduced pressure and the resulting residue was dissolved in dichloromethane (50 mL) and washed with water, saturated ammonia chloride, brine, dried over sodium sulfate and concentrated. The residue was purified by silica gel chromatography, eluting with 1:1 hexane-ethyl acetate, to give V (640 mg, 85%) as a white foam. 1H NMR (500.1 MHz) (CD3Cl) δ: 5.50 (m, 2H), 5.03 (t, J=10.5 Hz, 1H), 4.90 (m, 1H), 4.24 (m, 1H), 3.35 (m, 2H), 2.12 (s, 3H), 2.05 (s, 3H), 2.02 (s, 3H). 13C NMR (125.8 MHz) (CDCl3) δ: 170.26, 170.23, 169.78, 89.98, 71.09, 69.71, 68.34, 51.05, 20.68, 20.62, 20.58.
