Direct pyridazine ring synthesis from β-cyano esters. A facile synthesis of the derivatives of tetrahydro-3,6-pyridazinedione 3-hydrazone

Article abstract of DOI:10.1080/00397919308011225

4-Substituted tetrahydro-3,6-pyridazinedione 3-hydrazones (2) (or their 3-hydrazino tautomers 3), useful intermediates in the synthesis of bicyclic pyridazine derivatives, were prepared in satisfactory yields in the reaction of the corresponding alkyl 3-s
