A green reaction of isatins, active cyanomethanes, and cyclic 1,3-dicarbonyl derivatives for the efficient and simple one-pot three-component synthesis of spirooxindole fused heterocycles in refluxing water by use of magnetically recoverable and reusable catalyst is reported. The features of this procedure are, the use of magnetically recoverable and reusable catalyst, mild reaction conditions, high
据报道,通过使用可磁回收和可重复使用的催化剂,靛红,活性氰基甲烷和环状1,3-二羰基衍生物在回流水中进行高效,简单的一锅三组分合成螺环吲哚稠合杂环的绿色反应。该方法的特点是,使用可磁回收和可重复使用的催化剂,温和的反应条件,高至优异的产品收率,操作简便和后处理程序容易。最重要的是,催化剂容易的磁分离消除了反应完成后对催化剂过滤的需要。此外,即使重复使用5次,催化剂也保持高活性。
