We report here an operationally simple, palladium-catalyzed cyclization reaction of N-aryl imines, affording indoles via the oxidative linkage of two C-H bonds under mild conditions using molecular oxygen as the sole oxidant. The process allows quick and atom-economical assembly of indole rings from inexpensive and readily available anilines and ketones and tolerates a broad range of functional groups
我们在此报告了一种操作简单、钯催化的 N-芳基亚胺环化反应,在温和条件下使用分子氧作为唯一氧化剂,通过两个 CH 键的氧化连接得到吲哚。该过程允许从廉价且容易获得的苯胺和酮中快速且原子经济地组装吲哚环,并能耐受广泛的官能团。
