A selective functionalization of C–C═C bonds toward N–C═O bonds is realized by an n-Bu4NI-catalyzed reaction of 3-methylindoles with primary amines using TBHP as the unique oxidant. The systematic process involves oxygenation, nitrogenation, ring-opening, and recyclization, affording a broad range of quinazolinones in good to excellent yields.
的朝N-C = O键的C-C = C键的选择性官能化是通过实现Ñ -Bu 4 3- methylindoles使用TBHP作为唯一氧化剂伯胺NI-催化反应。系统的过程涉及氧合,硝化,开环和再循环,从而以良好或优异的收率提供了多种喹唑啉酮。
