An efficient and practical iodine-catalyzed oxidative functionalization of azaarenes with benzylicC–Hbonds via an N-alkylation and amidation cascade is developed to provide isoquinolin-1(2H)-ones. This method utilizes readily available unfunctionalized azaarenes and methylarenes as starting materials and proceeds under metal-free conditions with good to excellent yields, avoiding the use of expensive
通过N-烷基化和酰胺化级联反应,开发了一种有效且实用的碘催化的氮杂芳烃与苄基CH键的氧化功能化反应,以提供异喹啉-1(2 H)-one。该方法利用容易获得的未官能化的氮杂芳烃和甲基芳烃作为起始原料,并在无金属条件下以良好或优异的收率进行,避免了使用昂贵的贵金属催化剂以及避免产生卤化物和金属废物。该反应的合成效用以异吲哚并[2,1 - b ]异喹啉-7(5 H)-one的简明两步合成为例。

We describe the simple and efficientsynthesis of N-substituted isoquinolin-1-one derivatives. Initiating with the coupling of benzoic acids containing vinyl ethers with different amines, followed by rapid intramolecular cyclization under acidic conditions at room temperature, N-substituted isoquinolin-1-ones were furnished in high yields. The utility of this simple and mild cyclization method was
