摘要：

Glycosylation of various carbohydrate mono- and di-hydroxy derivatives with 2,3,4-tri-O-benzoyl-alpha-L-fucopyranosyl bromide under Helferich conditions is stereoselective for acceptors that contain an axial hydroxyl group and/or neighbouring acyloxy, phthalimido, or bulky monosaccharide substituents.
