Regioselective glycosylation of alcoholic hydroxyl and phenolic hydroxyl

A novel method for regioselective glycosylation of alcoholic hydroxyl and phenolic hydroxyl of polyhydroxyl compounds with the appropriate choice of the different reaction conditions has been developed.Alcoholic hydroxyl was selectively glycosylated using Ag2CO3/DCM catalyst system, while usingAg2CO3/quinoline catalyst system phenolic hydroxyl was selectively glycosylated.
