摘要
The preparation of alpha(1,2)-, alpha(1,3)- and alpha(1,6)-linked mannose disaccharides is described. The protected alpha-D-Man(1-->3)-D-Man disaccharide was synthesized using the trichloroacetimidate method, while the Konigs-Knorr procedure was employed in the preparation of the 1-->2- and 1-->6-linked disaccharides. Glycosylation of N-alpha-Fmoc-Ser-OPfp, N-alpha-Fmoc-Thr-OPfp and N-alpha-Fmoc-Hyp-OPfp with the dimannosyl bromides afforded the activated building blacks, in moderate to high yield, for direct use in solid-phase synthesis of glycopeptide libraries.
