Dimethylformamide: An Unusual Glycosylation Modulator

Abstract

A simple solution: When N,N-dimethylformamide was used to direct the stereochemical course of glycosylation reactions, 1,2-cis glycosylation products were formed with excellent selectivity. A straightforward highly α-stereoselective glycosylation involving preactivation (see scheme) should find broad application and be especially useful for sequential glycosylation reactions to form oligosaccharides.
