Stereoselective Glycosylation of Amides with Glycal Catalyzed by a Solid–Liquid Phase-Transfer and Proton-Transfer Dual-Functional Pyridinium Catalyst
2-Deoxyglycosylamides have great potential for biochemical applications, but their streamlined synthesis remains underexplored. Herein, 2-pentafluorophenylpyridinium tetrafluoroborate was designed for highly stereoselective glycosylation of amides with glycals. Besides the challenging substrates like glucals, the met...
