An efficient, clean, atom-economical and simple method for the one-pot synthesis of novel spirooxindole derivatives via a three-component reaction of isatins, dimedone and anilinolactones was reported. This reaction was performed by using MnFe2O4 nanoparticles (5 mol%) as an efficient magnetically heterogeneous catalyst in water as green solvent. Prominent among the advantages of this method is the
据报道,一种高效,清洁,原子经济,简单的方法,可通过靛红,二甲双酮和苯胺内酯的三组分反应,一锅合成新型螺氧杂吲哚衍生物。通过使用MnFe 2 O 4纳米颗粒(5 mol%)作为有效的磁性非均相催化剂,在水中作为绿色溶剂来进行该反应。该方法的优点中最突出的是使用了磁性可回收和可重复使用的催化剂,简单的后处理程序,良好或较高的产品收率以及使用水作为溶剂被认为对环境无害。
