intramolecular cyclocarbonylation of allylamines. [Pd(Xantphos)I2], which features a very large bite angle, has been found to facilitate the rapid carbonylation of azaarene‐substituted allylamines into bioactive quinolizinones in good to excellent yields. This transformation represents the first dearomative carbonylation and is proposed to proceed by palladium‐catalyzed CN bond activation, dearomatization
生物活性喹啉嗪酮的一种根本上新颖的方法是基于钯催化的烯丙基胺的分子内环羰基化反应。已发现[Pd(Xantphos)I 2 ]具有很大的咬合角,可促进氮杂芳烃取代的烯丙胺快速羰基化为具有良好收率的生物活性喹啉并酮。该转变代表了第一个脱芳基羰基化反应,并建议通过钯催化的CN键活化,脱芳香化作用,CO插入和Heck反应来进行。
