Herein is introduced the application of "super-electron-donor"(SED) 2-azaallyl anions in a tandem reduction/radical cyclization/radical coupling/aromatization protocol that enables the rapid construction of isoquinolines. The value of this transition-metal-free method is highlighted by the wide range of isoquinoline ethyl amines prepared with good functional group tolerance and yields. An operationally simple gram scale synthesis is also conducted, confirming the scalability.
本文介绍了“超电子给体”（SED）2-氮杂烯丙基阴离子在串联还原/自由基环化/自由基偶联/芳构化反应中的应用，该反应能够快速构建异喹啉。这种无过渡金属方法的价值体现在制备的一系列异喹啉乙胺具有广泛的官能团耐受性和良好的产率。还进行了操作简单的克级合成，证实了其可扩展性。
