SELECTIVE CLEAVAGE OF ESTER TYPE GLYCOSIDE-LINKAGES AND ITS APPLICATION TO STRUCTURE DETERMINATION OF NATURAL OLIGOGLYCOSIDES

Article abstract of DOI:10.1016/S0040-4039(01)81487-8

On treatment with anhydrous LiI, 2,6-lutidine and anhydrous methanol, an ester type glycosyl linkage of acidic tri- and di-terpenes was selectively cleaved without decomposition of a reducing terminal of the resulting sugar moiety to give an anomeric mixture of methyl glycosides along with an aglycone or a pro-aglycone in quantitative yield.In this reaction, no hydrolysis of any other glycoside linkages took place.
