A series of linear tetrapeptides and macrocyclic pentapeptides has been synthesized starting with N,N-bis(1-carboxy-2-substituted)-3,5-diaminocarbonyl)pyridine and N,N-bis(1-hydrazonyl-2-substituted)-3,5-diaminocarbonyl)pyridine. Structures of newly synthesized compounds were elucidated by IR, H-1 and C-13 NMR, and MS spectral data and elemental analysis.
