approach for the synthesis of 4-(1H-indol-3-yl)thieno[2,3-d]pyrimidine derivatives has been accomplished via the heteroarylation of 4-chloro thieno[2,3-d]pyrimidines with a range of indoles. The reaction was performed using AcOH as a promoter as well as solvent to give the corresponding products in good to acceptable yields. This metal free method proceeded via the CC bond forming reaction and offers advantages
通过4-氯噻吩并[2,3- d ]嘧啶与吲哚范围。该反应使用AcOH作为促进剂以及溶剂进行,以良好到可接受的收率得到相应的产物。这种无金属方法通过CC键形成反应进行,具有条件简单、持续时间短、使用环保能源等优点。除了其缺点之外,还通过合成的化合物的药用价值展示并举例说明了该方法的有用性。化合物3i和3j在体外表现出良好的TNF-α抑制作用,被确定为初始命中分子。
