A short new route to the pyrido[2,3,4-kl]acridine ring system has been developed from readily available quinoline precursors involving two key steps: (i) a palladium(0)-catalysed Suzuki cross-coupling reaction of 4-chloroquinolines with arylboronic acids, and (ii) an intramolecular nitrene insertion reaction of the nitrenes derived from 4-phenyl-5-azidoquinolines.
吡咯并[2,3,4- kl ] ac啶环系统的一条短途新路线已经从容易获得的喹啉前体中开发出来,涉及两个关键步骤:(i)钯(0)催化的Suzuki交叉偶联反应是4-氯喹啉与芳基硼酸,和(ii)衍生自4-苯基-5-叠氮喹啉的腈的分子内腈插入反应。
