A new strategy for the synthesis of 3-diarylmethyl indoles was developed through FeCl3 as Lewis acid catalyzed three-component aza-Friedel–Crafts reactions of indoles, aldehydes, and tertiary aromatic amines in one-pot. The reactions generated the corresponding 3-diarylmethyl indoles in good yields under mild reaction conditions by using less expensive, readily available, and environmentally benign
通过路易斯酸催化一锅合成吲哚,醛和叔芳族胺的三组分氮杂-弗里德尔-克来夫特反应,通过FeCl 3提出了一种新的3-二芳基甲基吲哚合成策略。通过使用较便宜,易于获得且对环境无害的铁催化剂,该反应在温和的反应条件下以高收率产生了相应的3-二芳基甲基吲哚。重要的是要注意,此反应的关键特征是操作简便。
