The development of multicomponent reactions for indole synthesis is demanding and has hardly been explored. The present study describes the development of a novel multicomponent, cascade approach for indole synthesis. Various substituted indole derivatives were obtained from simple reagents, such as unfunctionalized alkenes, diazonium salts, and sodium triflinate, by using an established straightforward
用于吲哚合成的多组分反应的开发是需要的,并且几乎没有被探索。本研究描述了吲哚合成的新型多组分,级联方法的发展。通过使用已建立的直接和区域选择性方法,可以从简单的试剂(例如未官能化的烯烃,重氮盐和三氟甲磺酸钠)中获得各种取代的吲哚衍生物。该方法是基于烯烃的自由基三氟甲基化作为费歇尔吲哚合成的入口。除了吲哚合成外,还描述了多组分级联反应在吡唑和哒嗪酮合成中的应用。
