The synthesis of eight new diazopeptides by aprotic diazotisation with N2O4 is described for glycylglycine, triglycine, pentaglycine, L-leucylglycine and the ethyl esters of L-leucylglycine, L-alanylglycine, L-serylglycine and L-threonylglycine.The diazo derivatives (7) - (10) of the parent peptides are isolated as calcium salts.The UV-vis., IR, 1H NMR and MS properties of the new diazopeptides are reported together with those for the diazo derivative of glycylglycine ethyl ester and glycylglycinamide.
