Although such ionic glycosylation strategies can effectively form O-glycosides, their use in N-glycoside synthesis is often plagued by the subdued reactivity of N-nucleophiles under the acidic reaction conditions required for glycosyl donor activation. Exploration of the reactivity of glycosyl radical ...
