pharmaceuticals. However, the direct intramolecular radical cyclizations of the corresponding amide compounds favor 5-exo products 2. Reports on the radical cyclization reactions producing 3,4-dihydroquinolin-2-one derivatives are limited. Herein, an efficient tandem reaction combining radical and ionic processes was developed, which provides a practical synthetic strategy for the synthesis of substituted
3,4-二氢喹啉-2-酮在药物领域中非常重要。然而,相应酰胺化合物的直接分子内自由基环化有利于5- exo产物2。关于产生3,4-二氢喹啉-2-酮衍生物的自由基环化反应的报道是有限的。本文中,开发了一种结合自由基和离子过程的有效串联反应,其为在中性反应条件下由简单易得的前体合成取代的3,4-二氢喹啉-2-酮提供了实用的合成策略。
