Properly protected hexasaccharide was synthesized by employing the glycosyl phthalate method from a trisaccharide acceptor and a trisaccharide donor, both of which were obtained by deprotection of a common trisaccharide precursor. Trisaccharide was prepared by assembly of three monosaccharide building blocks through two β-mannosyl linkages. The mannosyl phthalate donor for the disaccharide synthesis and the CB glycoside donor for the trisaccharide synthesis were achieved in the 4, 6-O-benzylidene directed β -mannosylation.
