(Chemical Equation Presented) Three bis(amino acids) linked by the amino groups have been prepared and structurally characterized. We have named them Gly-Gly, Ala-Ala and Gly-Ala (or Ala-Gly). These compounds have been characterized by NMR both in solution and in the solid state. They exist as zwitterions with the ammonium group proximal to the carboxylate anion. In the case of Gly-Ala, a dynamic situation is observed by CPMAS NMR (13C and 15N) corresponding to a double proton migration between two proximal tautomers.

The ruthenium tetroxide (RuO4) oxidation of the 3-substituted N,N'-diBochexahydropyridazines gave the 6-oxohexahydropyridazines in good to high yields, whereas the oxidation of the unsubstituted ones also gave the 3,6-dioxo derivatives. The 3,6
