Serine- and mannoside-derived thioesters and a mannosidic cysteine derivative were prepared to test native chemical ligation (NCL) for protecting-group-free synthesis of small glycopeptide clusters, which are valuable tools in the glycosciences. The glycopeptides and glycopeptide clusters, respectively, which were obtained via NCL, bear the potential for dimerization and other derivatization of the thiol functionality.
