Abstract

A novel, efficient and one-pot multi-component procedure for the synthesis of simple pyrano[3,2-]chromen-5(4)-ones or pyrazolyl pyrano[3,2-]chromen-5(4)-ones reaction of aryl aldehydes, acetophenones and 4-hydroxycoumarin promoted by amino glucose-functionalized silica-coated NiFeO nanoparticles under solvent-free conditions without using any other harmful organic reagents was reported. The structure of this nanoparticle was characterized by transmission electron microscopies, X-ray diffraction and Fourier transform infrared spectroscopies. The catalyst could easily be separated from the reaction mixture by using an external magnetic field and it was reusable. The high purity of the desired products, eco-friendliness, short reaction time and easy workup procedure can be mentioned as the other advantages of this method.

摘要

报道了一种新颖、高效的一锅多组分方法，用于在无溶剂条件下，由氨基葡萄糖功能化的二氧化硅包覆的NiFeO纳米颗粒促进芳醛、苯乙酮和4-羟基香豆素反应，合成简单的吡喃并[3,2 -]色烯-5(4)-酮或吡唑基吡喃并[3,2 -]色烯-5(4)-酮，且无需使用任何其他有害有机试剂。通过透射电子显微镜、X射线衍射和傅里叶变换红外光谱对该纳米颗粒的结构进行了表征。该催化剂可通过外部磁场轻松从反应混合物中分离出来，并且可重复使用。该方法的其他优点包括所需产物纯度高、环保、反应时间短以及后处理步骤简便。
