A facile method was developed for the synthesis of quinazolinone derivatives in a one-pot condensation reaction via in situ amine generation using ammonia as the amine source and with the formation of four new C–N bonds in good to excellent yields. With the optimised method, we synthesized a library of piperazine linked quinazoline derivatives and the synthesized compounds were evaluated for their
开发了一种简便的方法,通过使用氨作为胺源,通过原位生成胺,在一锅缩合反应中合成喹唑啉酮衍生物,并形成四个新的 C-N 键,产率良好至优异。通过优化的方法,我们合成了哌嗪连接的喹唑啉衍生物库,并评价了合成的化合物对结核分枝杆菌的抑制活性。化合物8b 、 8e 、 8f 、 8m 、 8n和8v显示出有效的抗分枝杆菌活性,MIC值为2-16 μg mL -1 。所有合成的化合物都遵循 Lipinski 的药物相似规则。
