An efficient synthesis of substituted indolizine and its benzo derivatives, pyrrolo[1,2-a]quinolines and pyrrolo[2,1-a]isoquinolines, by the reaction of allenyl ketones with α-bromo carbonyl compounds and pyridines (quinoline or isoquinoline) under mild conditions without an added oxidant other than molecular oxygen from air was developed. Notably, allenyl ketones with or without a substituent attached
通过烯基酮与α-溴代羰基化合物和吡啶(喹啉或异喹啉)反应,有效合成取代的吲哚嗪及其苯并衍生物吡咯并[1,2-a]喹啉和吡咯并[2,1-a]异喹啉在温和的条件下,除了来自空气的分子氧之外,没有添加氧化剂。值得注意的是,带有或不带有连接到丙二烯部分内部位置的取代基的丙二烯基酮提供了具有不同取代模式的吲哚嗪衍生物。
