Synthesis of New Pyrimidine, Quinazoline and Diazatricyclo Derivatives by Multicomponent Reaction and Evaluation of Their Biological Activity
Abstract A series of new pyrimidine and quinazoline derivatives was synthesized by a Biginelli-like reaction of urea/thiourea, aldehyde, and ketone in the presence of hydrochloric acid as a catalyst. In a similar way, some novel diazatricyclo derivatives were obtained via a Biginelli-like reaction followed by an intramolecular Michael-type addition. The yields of products were reasonable after recrystallization
摘要 以尿素/硫脲、醛、酮为原料,以盐酸为催化剂,通过类Biginelli反应合成了一系列新的嘧啶和喹唑啉衍生物。以类似的方式,通过类 Biginelli 反应和分子内迈克尔型加成获得了一些新的二氮杂三环衍生物。乙醇重结晶后产物收率合理。所有新合成的化合物均使用 IR 和 NMR(1H 和 13C)光谱和元素分析进行表征。研究了这些化合物对金黄色葡萄球菌(RTCC,1885)和大肠杆菌(ATCC,35922)的抗菌活性。补充材料可用于本文。转至出版商的在线版磷、硫、和硅和相关元素查看免费的补充文件。图形概要
