An efficient type I Ferrier rearrangement reaction system for the synthesis of 2,3-unsaturated-O-glycosides has been established by using TiCl3(OTf) as the catalyst. A series of 2,3-unsaturated-O-glucosides were prepared from 3,4,6-tri-O-acetyl-D-glucal in good yield and high anomeric selectivity. (C) 2013 Elsevier Ltd. All rights reserved.
