Abstract: Bi(OTf)₃ and SiO₂-Bi(OTf)₃ are found to effectively catalyze the Ferrierrearrangement of tri-O-acetyl glycals with different alcohols providing an effective routeto 2,3-unsaturated O-glycosides with good anomeric selectivity and good to excellentyields after short reaction times.

Keywords: Glycals; pseudoglycals; glycosidation; bismuth triflate; Ferrier rearrangement.
