Soluble polymers that can be readily isolated via precipitation and possess multiple amino acid attachment sites are highly attractive for peptidesynthesis. Polyethylene glycol supports that solubilize the growing peptide chain and can be readily isolated have been widely used for peptidesynthesis. However, a stoichiometric amount of the PEG support is required because each PEG support typically
This paper describes an original methodology for peptide bond synthesis avoiding toxic solvents and reactants. Ball-milling stoichiometric amounts of Boc-protected α-amino acid N-carboxyanhydrides (Boc-AA-NCA) or Boc-protected α-amino acid N-hydroxysuccinimideesters (Boc-AA-OSu) with α-amino acid alkyl ester salts in the presence of NaHCO3 and a minimal quantity of EtOAc led to the production of di-
