Synthesis of newheterocyclic compounds containing the pyridazinone moiety, which have a valuable biological activities, has been achieved through the nucleophilic addition of benzylamine to 4-(p-substituted phenyl)-4-oxo-2-butenoic acid , followed by cyclocondensation of the adducts to the corresponding pyridazin-3-one derivatives . The behavior of the latter compounds toward different nucleophilic
