A one-pot multicomponent facile synthesis of dihydropyrimidin-2(1H)-thione derivatives using triphenylgermane as a catalyst and its binding pattern validation
A series of substituted dihydropyrimidin-2(1H)-thione derivatives (1–8) have been synthesized using a facile and modified procedure with triphenylgermyl propionate as a catalyst. In comparison with the classical Biginelli reaction, this new protocol has the advantages of excellent yield and shorter reaction times. The synthesized compounds have been characterized by various spectroscopic techniques
一系列取代的二氢嘧啶-2(1 H)-硫酮衍生物(1-8)已使用丙酸三苯甲基锗酯作为催化剂,通过简便易行的合成方法合成。与经典的Biginelli反应相比,该新方案具有优异的收率和较短的反应时间的优点。合成的化合物已通过多种光谱技术进行了表征,例如FT-IR,多核(1 H / 13 C)NMR光谱和单晶XRD分析。进行了分子对接研究,以确定在人类拓扑异构酶IIα(4FM9)和幽门螺杆菌脲酶(1E9Y)酶的活性位点中强效抑制剂的可能结合方式。化合物根据分子对接分数和分子动力学模拟,发现3是最有效的抑制剂,这表明可以将其进一步加工为先导分子以解释这些化合物的药理特性。
