A facile method to convert thioglycosides to glycosyl fluorides with Ipy₂BF₄ (py = pyridine) is presented. Alternatively, activation of thioglycosides with Ipy₂BF₄ in the presence of acids and glycosyl acceptors led to glycosylation reactions. Perbenzylated (armed) glycosyl donors yielded predominantly the β-anomeric product. This methodology is compatible with one-pot sequential glycosylation.
