Diastereoselective synthesis of C‑vinyl glycosides via gold(I)-catalyzed tandem 1,3-acyloxy migration/Ferrier rearrangement
A novel gold-catalyzed C-glycosylation has been developed to gain access to α,(Z)-selective C-vinyl glycosides, starting from readily available glycals and propargylic carboxylate. This reaction involves a tandem intermolecular gold-catalyzed 1,3-acyloxy migration/Ferrier rearrangement with the invo...
