beta-selective glycosylation of 5-thioglucopyranose derivatives; Syntheses of beta-(1 -> 6) linked 5'-thioglucopyranosyl disaccharides
beta-Stereoselctive and effective glycosylation with 5-thioglucopyranose was achieved by performing the reaction with pivaloyl- or benzoyl-protected glucopyranosyl trichloroacetimidates and BF3OEt2, a glycosyl activator, when C6-OH glucopyranosyl or galactopyranosyl derivatives were employed as acceptors.
