摘要

Methyl and benzyl 2, 3, 4-tri-O-benzyl-D-glucopyranuronates, prepared from D-glucurono-6, 3-lactone, afforded selectively the corresponding α-glucopyranosiduronates by the aid of the condensing reagent system composed of p-nitrobenzenesulfonyl chloride, silver trifluoromethanesulfonate, and triethylamine. Using this method, O-α-D-glucopyranuronosyl- (1→ 3)-O-α-L-arabinofuranosyl-(1→ 3)-D-xylopyranose, one of the minimal component ...
