Heterocyclic Analogues of Phthalhydrazides: Cyclic Hydrazides of Pyridine 1-Oxide and Pyrazine 1,4-Dioxide Dicarboxylic Acids

The synthesis of N-oxides of the cyclic hydrazides of pyridine and pyrazine o-dicarboxylic acids is described.Pyridopyridazine-5,8-dione 1-oxide, pyridopyridazine-1,4-dione 6-oxide, and pyrazinopyridazine-5,8-dione 1,2-dioxide, were obtained by direct oxidation of the parent hydrazides with peracetic acid.The pyridopyridazine derivatives were also unambiguously synthesized by treating the anhydrides or diesters of the relevant carboxylic acid 1-oxides with hydrazine hydrate.
