| Abstract: | Glycosylation of various glycosyl acceptors with 2'-carboxybenzyl (CB) 2,3,4,6-tetra-O-benzyl-beta-D-glucopyranoside and CB 2,3,4,6-tetra-O-benzyl-alpha-D-mannopyranoside as glycosyl donors afforded alpha-C-glycosides exclusively or predominantly in good yields. CB glycosides were also converted to other well-known glycosyl donors, the corresponding phenyl thioglycoside and the glycosyl fluoride derivatives. |
