Alternatively, activation of thioglycosides with Ipy(2)BF(4) in the presence of acids and glycosyl acceptors led to glycosylation reactions. Perbenzylated (armed) glycosyl donors yielded predominantly the beta-anomeric product. This methodology is compatible with one-pot sequential glycosylation. ((C) Wiley-VCH Verlag GmbH & Co. 收起
