Reaction Steps

A solution of 250 mg of 2,3,4,5,6-penta-O-acetyl-D-gluconic acid (benzyl 3,4-di-O-acetyl-2-benzyloxycarbonylamino-2,6-didesoxy-a-D-glucopyranosid-6-yl)-amide in 20 ml of dioxan and 2 ml water was hydrogenated at room temperature in the presence of palladium on charcoal (10%). After 2 hours, the catalyst was filtered off over a filter aid and the filtrate was concentrated. The residue was crystallized from ethyl acetate/ether and gave 2,3,4,5,6-penta-O-acetyl-D-gluconic acid (benzyl 3,4-di-O-acetyl-2-amino-2,6-didesoxy-a-D-glucopyranosid-6-yl)-amide, [a]+96.0° (c 0.2; dioxan), MS: m/z 741.1 ([M+H]+).
