The intramolecular hydroaminocarbonylation of alkenes is a compelling tool to rapidly access lactam, a privileged motif ubiquitous in natural products, pharmaceuticals, and agrochemicals. However, selective carbonylation to bridged polycyclic lactams with a lactam nitrogen at a bridgehead position is less explored. We herein report a modular palladium-catalyzed approach to perform a tandem hydrocarbonylative
烯烃的分子内氢氨基羰基化是快速获得内酰胺的有力工具,内酰胺是天然产物、药物和农用化学品中普遍存在的一种特殊基序。然而,在桥头位置具有内酰胺氮的桥接多环内酰胺的选择性羰基化研究较少。我们在此报告了一种模块化的钯催化方法,用于与 2-乙烯基芳基醛亚胺、烯烃和 CO 进行串联烃基化内酰胺化/Diels-Alder 环加成反应,这为以高产率和高选择性提供桥接多环内酰胺提供了便利。
