•Synthesis of a set of protected neoglycopeptides are reported.•They include di-, tri-, tetra- & pentavalent scaffolds bearing upto 10 sugar units.•Intended to derive potential inhibitors for cholera toxin/other analogous proteins.•Sugars are attached by glycosylation to cyclic/acyclic backbone structures.
Synthesis of a set of novel glycopeptide analogues as potential cholera/cholera-like toxin inhibitors in their protected form is described. They include di-, tri-, tetra- and pentavalent scaffolds. The synthetic steps were achieved using a combination of solvent-free mechanochemical as well as the conventional solution-phase reactions. During the conventional DIC-HOBt-mediated peptide coupling followed for the preparation of certain glycopeptide analogues an interesting in situ Fmoc deprotection was observed which has been demonstrated to hold potential for synthesiszing glycopeptides/neoglycopeptides with extended polyamide chains.
