been developed for the synthesis of bis-coumarins by using a reasonably lesser quantity of Amberlite IR-120 through Domino Knoevenagel–Michael reaction. In which, a series of aryl aldehydes have efficiently reacted with 4-hydroxycoumarin to give respective bis-coumarins through a short reaction time. The acidic Amberlite IR-120 catalyst used for a reaction was isolated and reused for successive four reactions
在温和的条件下,通过 Domino Knoevenagel-Michael 反应,使用合理较少的 Amberlite IR-120 合成双香豆素,开发了一种环境友好的方法。其中,一系列芳醛与4-羟基香豆素有效反应,通过较短的反应时间得到相应的双香豆素。用于反应的酸性 Amberlite IR-120 催化剂被分离出来并重新用于连续的四个反应。根据观察结果,回收催化剂的活性得以保留。在体外双香豆素对两种癌细胞系的检查证明,其中一些已经显示出有希望的抗增殖特性。双香豆素衍生物与GlcN-6-P合酶的分子对接研究产生了与标准药物氯喹相比具有预期结合能、对接能、抑制常数和静电能的潜在构象。
