Stereoselective O-glycosylation reactions employing diphenylphosphinate and propane-1,3-diyl phosphate as anomeric leaving groups

Abstract

Glycosidation of tetra-O-benzyl-D-glucose using diphenylphosphinate as the leaving group afforded β-O-linked glycosides as the major products, whilst the use of propane-1,3-diyl phosphate as the leaving group resulted in the exclusive formation of β-O-linked glycoside.
