Conformationally Restricted GalN3 Donors Enable Zinc(II)-Mediated Stereocontrolled Galactosylation

Abstract We report a Zn(II)-mediated stereocontrolled galactosylation with two conformationally restricted GalN3 donors that enables divergent α- and β-glycosylation. The 4,6-O-TIPDS/3-O-Bz donor selectively affords α-GalN3 glycosides, while the 4,6-O-benzylidene/3-O-TIPS donor p...
