Reaction Steps

A mixture of 20b (220 mg, 0.41 mmol) and Pd-C (10%, 55 mg) in ethanol (3 mL) was vigorously stirred under H2 at room temperature for 1 h. After the catalyst was filtered off, the filtrate was concentrated in vacuo. The residue was recrystallized from diethyl ether to give 20a (177 mg, 97%) as fine needles, mp 132-133° C.; [α]25D+374° (c 0.88, CHCl3). Its 1H NMR spectrum (C6D6) was identical with that reported previously by Unger et al. (Carbohydr. Res. 1980, 80, 191).
