α-Fucosylation by 2,3,4-tri-O-benzoyl-α-L-fucopyranosyl bromide under Helferich conditions

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

Synthesis of di-O-glycosyl derivatives of methyl α-L-rhamnopyranoside

The syntheses are described of 2,3-di-O-glycosyl derivatives (1-12) of methyl α-L-rhamnopyranoside where the glycosyl moieties are variously α-L-fucopyranose, β-L-fucopyranose, β-D-glucopyranose, α-D-mannopyranose, and α-L-rhamnopyranose.The syntheses inv
