Participants

Reaction Steps

482 mg (0.843 mmol)of 1,6-anhydro-3,4-di-O-acetyl-2-deoxy-2 -[1D(1N,2,4/3)-(2,3,4-tri-O-acetyl-5-C-acetoxymethyl-2,3,4-trihydroxy-5-cyclohexen-1-yl)amino]-β-D-glucopyranose (compound 4) was dissolved in dry methanol (20 ml) and a methanolic solution of sodium methoxide (0.5N, 0.1 ml) was added. After 4 hours, solvent was evaporated and the residue was purified by passing through a column of sephadex using water:ethanol (1:1) as eluent to provide pure 1,6-anhydro-2-deoxy-2-[1D-(1N,2,4/3)-5-C-hydroxymethyl-2,3,4-trihydroxy-5-cyclohexen-1-yl)amino]-β-D-glucopyranose (compound 5) (249 mg, 92.5%) as white powder after lyophilization.
