In this study, a new series of quinazoline and their annulated derivatives have been synthesized. A number of quiazolinone derivatives substituted at position-3 were prepared from 3, 1-benzoxazinone by the treatment of 3,1-benzoxazinone with different nitrogen nucleophiles such as, hydrazine hydrate, phenylhydrazine, ethanolamine, and cyano acetohydrazide afforded the quinazolinone derivatives 7–11.
摘要 本研究合成了一系列新的喹唑啉及其环状衍生物。通过用不同的含氮亲核试剂如水合肼、苯肼、乙醇胺和氰基乙酰肼处理 3,1-苯并嗪酮,从 3,1-苯并嗪酮制备了许多 3 位取代的喹唑啉酮衍生物,得到喹唑啉酮衍生物 7- 11. 酰肼衍生物 5 与芳香醛反应得到席夫碱衍生物 16a-c。一些合成的化合物针对乳腺癌细胞系 (MCF-7) 进行了测试。所有新合成化合物的结构均基于 IR、1H、13C NMR、质谱数据和元素分析。图形概要
