4-Aminopyridazin-3(2H)-ones substituted at position 5 with a variety of oxygenated carbon chains were obtained in good yields by reductive opening of the pentatomic ring of isoxazolopyridazinones (1).Starting from ethyl 4-acylisoxazole-3-carboxylat

Treatment of isoxazolopyridazin-7(6H)-ones (1a-d) with hydrazine afforded the pyrazole derivatives (3a-d) which were converted in high yields into the new pyrazolopyrimidopyridazin-7-(8H)-ones (4a-d) by ring-closure with acetic an
