isoindolinone derivatives were developed to synthesize nuevamine, a cyano-chilenine derivative, and two related analogs. A copper-catalyzed C–H cross-dehydrogenative coupling (via cation formation) allowed the formation of a new C–C bond leading to the direct assembly of the isoindolo[1,2-a]isoquinolinone tetracyclic system of the nuevamine. The syntheses of the cyano-chilenine derivatives were carried
开发了异吲哚啉酮衍生物的发散 C(sp 3 )-H 键官能化来合成 nuevamine、氰基-辣椒碱衍生物和两种相关的类似物。铜催化的 C-H 交叉脱氢偶联(通过阳离子形成)允许形成新的 C-C 键,从而直接组装新胺的异吲哚[1,2- a ]异喹啉酮四环系统。氰基 - 辣椒碱衍生物的合成是通过在碱性条件下安装两个腈基团(通过阴离子形成)。然后,通过 Houben-Hoesch 环化过程构建了 chilenine 骨架的异吲哚并苯并氮杂系统。本方法具有不需要使用预功能化基材的优点。
