Methyl and benzyl 2,3,4-tri-O-benzyl-d-glucopyranuronates, prepared from d-glucurono-6,3-lactone, afforded selectively the corresponding a-glucopyranosiduronates by the aid of the condensing reagent system composed of p-nitrobenzenesulfonyl chloride, silver trifluoromethanesulfonate, and triethylamine. Using this method, O-a-d-glucopyranuronosyl-(1?3)-O-a-l-arabinofuranosyl-(1?3)-d-xylopyranose, one of the minimal component units in the structure of plantago-mucilage A from the seeds of Plantago asiaticaLinné constituting a Chinese medicine : chegianzi []. |
