摘要：

Er(OTf3 is a useful catalyst for the Ferrier rearrangement furnishing high yields of O- and S-glycosides. The transforination has wide applicability, cleaner reaction profiles, mild reaction conditions, and high stereoselectivity and the catalyst, which is also commercially available, can be recovered and reused.
