with hydrazine hydrate to obtain the newfused bicyclic 4-aryl-5-hydrazinyl-3-(1-hydrazonoethyl)-1-phenyl-1,4-dihydropyrimido[4,5-c]pyridazines via the Dimrothrearrangement is reported. Further cyclisation was achieved by the treatment of latter compounds with triethyl orthoformate to afford several derivatives of a novel tetracyclic fused system [1,2,4] triazolo[4″,3″:1′,6′]pyrimido[4′,5′:3,4]pyridazino[1

series of 3‐amino‐2,5‐dihydropyridazines and fused pyridazinoquinazolines have been prepared in a one‐step procedure from three‐component reactions of (arylhydrazono)‐propan‐2‐ones, aldehydes and malononitrile or ethyl cyanoacetate in the presence of magnesiumoxide (MgO) and 12‐tungstophosphoric acid (PW) as highly effective heterogeneous catalysts. The salient features of these methods include high

1-Arylhydrazonopyruvaldehydes 1 react with α,β-unsaturated nitriles 2 to yield 6-amino-1,4-dihydropyridazines 4 that are converted into pyridazinones 5 via refluxing in an acetic acid/hydrochloric acid mixture and into the ethylidenemalononitrile derivatives 6 on reflux with malononitrile in ethanolic/piperidine solution.
