Abstract New three-component reaction was developed via one-pot strategy for the synthesis of functionalized 3,3′-disubstituted oxindoles and spirooxindole through the reaction among isatin, malononitrile, and acetone/indole/nitromethane/acetylacetone/dimedone in ethanol as solvent without base. It was observed that all the mixed ligand transition metal complexes with triphenylphosphine worked as the
摘要 通过一锅法开发了新的三组分反应,通过靛红、丙二腈和丙酮/吲哚/硝基甲烷/乙酰丙酮/二甲酮在无碱乙醇溶剂中的反应合成功能化的 3,3'-二取代羟吲哚和螺吲哚. 观察到所有与三苯基膦的混合配体过渡金属配合物均作为有效催化剂起作用。本方法具有几个优点,包括催化剂的制备和处理简单,后处理简单易行,反应时间短,产物收率高。 图形概要
