Synthesis of a novel heterocyclic ring system: 4-substituted-1-thioxo[1,2, 4,5]tetraazino[1,2-b]phtalazine-6,11-dione

Article abstract of DOI:10.1515/HC.2007.13.5.311

1,4-dioxo-3,4-dihydro-2(1H)phtalazinecarbothiohydrazide 3 was initially synthesized by reaction of phtalic anhydride with thiocarbohydrazide. Compounds 4a-e with the novel heterocyclic ring system of 4-substituted-1-thioxo-1,2- dihydro[1,2,4,5]tetraazino[1,2-b]phtalazine-6,11-dione were subsequently synthesized by cyclocondensation of 3 with trimethyl orthoformate, trimethyl orthoacetate, benzoic anhydride, cyanogen bromide and carbon disulfide, respectively.
