short reaction time, operational simplicity, and highly efficient reaction system. This protocol, which produces water as the only byproduct, provides efficient and atom-economical access to a class of fascinating quinoline and isoquinoline products in satisfactory yields. The method is effective on the gram scale, thus highlighting the inherent practicality of this methodology.
介绍了一种新的、绿色的、无过渡金属的方案,用于在Na 2 S 2 O 8存在下,从容易获得且对环境无害的喹啉和异喹啉N-氧化物与炔丙醇开始,用于轻松修饰喹啉和异喹啉衍生物或 K 2 S 2 O 8在 100°C。一锅转化具有官能团相容性好、反应时间短、操作简单、反应体系高效等优点。该协议产生水作为唯一的副产品,提供了以令人满意的收率获得一类引人入胜的喹啉和异喹啉产品的高效和原子经济的途径。该方法在克尺度上是有效的,从而突出了该方法的内在实用性。
