The synthesis of a suitably protected sugar amino acid (δ-glyco-amino acid) as a building block to be incorporated into the peptide chain (N-terminus) of bioactive peptide analogues is described. Its efficient coupling reactions with pilot amino acids as well as dipeptides have been accomplished by standard peptide chemistry.
