An efficient method for the conversion of 2,4,6-tri-O-acetyl-D-glucal to 2,3-unsaturated glycosides by using triflic acid on SiO2 as catalyst has been established. A series of 2,3-unsaturated glucosides were synthesized in good yield and high anomeric selectivity under transition metal-free conditions. (c) 2012 Elsevier Ltd. All rights reserved.
