摘要

Despite the previous literature describing the “low-to-modest” efficiency, the readily available C5-acetamide donor was reinvestigated for its use in α-sialylation under microfluidic conditions. The N-phenyltrifluoroacetimidate donor was efficiently mixed with an appropriate amount of TMSOTf to produce the α (2–6) and α (2–3)-sialylation products of galactose and glucosamine acceptors in excellent yields and with nearly perfect α- ...
