A green cascade three-component reaction between 4-hydroxycoumarin, malononitrile and a wide range of arylaldehydes by employing molybdenum oxide nanoparticles (MoO3 NPs) is described. By this achievement, some medicinally important products have been successfully synthesized in a one-pot under green conditions. Obtaining good to excellent yields of products, environmentally benign procedure, being
描述了通过使用氧化钼纳米颗粒(MoO 3 NPs)在4-羟基香豆素,丙二腈和各种芳基醛之间进行绿色级联三组分反应。通过这一成就,在绿色条件下一锅成功地合成了一些具有医学重要性的产品。获得良好或优异的产品收率,环境友好的程序,易于处理,原材料的可用性,使用无毒溶剂以及纳米催化剂的高回收率是这种方法的最重要优势。
