nucleophiles namely, hydrazine hydrate, in different solvents, ammonium acetate, and o-phenylenediamine has been investigated to give aminoquinazolin-4-one, benzotriazepinone, spiro-type compound, and nitrogen bridgehead compounds 3-5, respectively. Also, reactivity of the aminoquinazolin-4-one 2 towards carbon elec-trophiles such as ethyl acetoacetate, ethyl phenylacetate, ethyl chloroacetate, and aromatic
2-(4-氧代-4 H-苯并[ d ] [1,3]恶嗪-2-基)-苯甲酸(1)在不同溶剂,乙酸铵和邻苯二胺中对氮亲核试剂水合肼的行为已经研究了苯二胺,分别得到氨基喹唑啉-4-酮,苯并三氮杂酮,螺环型化合物和氮桥头化合物3-5。而且,已经讨论了氨基喹唑啉-4-酮2对碳亲电子试剂如乙酰乙酸乙酯,苯基乙酸乙酯,氯乙酸乙酯和芳族醛的反应性。Schiff碱8与硫亲核试剂即o的反应-氨基硫酚和/或硫代乙醇酸可得到迈克尔型加合物。产品1-24的结构分配已通过元素分析和光谱数据(1 H-和13 C -NMR和MS碎片)证实。生物测定表明,所获得的一些目标化合物具有良好的选择性抗癌活性。
