A novel silyl linker: Motif for side chain tethered approach to solid-phase glycopeptide synthesis

In order to facilitate the solid-phase syntheses of protected glycopeptide blocks, we designed a novel silyl linker, which allows the alcoholic side chain (carbohydrate, serine, or threonine) of (glyco-)peptides to link to the solid support. Utilizing this linker, peptide coupling reactions at both the N- and the C-termini were successful. Synthesis of the glycophorin AM fragment corresponding to the N-terminal glycoheptapeptide is demonstrated. (C) 1999 Elsevier Science Ltd. All rights reserved.
