摘要：

Sc(OTf)(3) was found to be an efficient catalyst for the C-glycosylation of phenols. Reactions of various functionalized phenols and glycosyl acetates, including an azido-bearing one, are achieved by using a catalytic amount of Sc(OTf)(3) (10 mol% for neutral sugars or 50 mol% for an azido sugar) under mild conditions.
