Thiazolo 3 a–c and oxothialo 5 a–b pyrimidine compounds were synthesized by a simple one-pot condensation reaction of the pyrimidine derivative i 1a and 1,2-dibromoethane i 2 or 2-bromopropanoic acid 4 . In a similar way the thiazepinopyrimidine compounds 7 (a–b) were synthesized by reaction of 1b and 1,4-dichlorobutane 6 in dimethylformamide under reflux condition. The yields of products following
通过嘧啶衍生物 i 1a 和 1,2-二溴乙烷 i 2 或 2-溴丙酸 4 的简单一锅缩合反应合成了噻唑并 3 a-c 和氧噻唑 5 a-b 嘧啶化合物。以类似的方式,硫氮杂嘧啶化合物 7 (a-b) 是通过 1b 和 1,4-二氯丁烷 6 在二甲基甲酰胺中在回流条件下反应合成的。重结晶后产物的产率约为 60-80%。
