Treatment of glycals with trialkylaluminum in the presence of a catalytic amount of Yb(OTf)(3) leads to the corresponding alkyl 2,3-unsaturated glycosides in good to excellent yields. Reactions of protected glycals are achieved under very mild conditions. (C) 2009 Elsevier Ltd. All rights reserved.
