Synthesis of new heterocyclic 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
已经通过亲核加成完成了具有有价值的生物活性的含有哒嗪酮部分的新杂环化合物的合成。苄胺转化为4-(对位取代苯基)-4-氧代-2-丁烯酸,然后加合物的环缩合 相应的哒嗪-3-酮衍生物 。研究了后者化合物对不同亲核试剂和亲电试剂的行为。通过元素分析和光谱数据阐明了新合成化合物的结构。J.杂环化学。(2010)。
