The palladium-catalyzed annulation of arynes by substituted o-halobenzamides produces N-substituted phenanthridinones in good yields. This methodology provides this important heterocyclic ring system in a single step by simultaneous C–C and C–N bond formation, under relatively mild reaction conditions, and tolerates a variety of functional groups.
通过取代的邻卤代苯甲酰胺钯催化的芳炔环化以良好的产率产生N-取代的菲啶酮。该方法通过在相对温和的反应条件下同时形成 C-C 和 C-N 键,一步提供了这种重要的杂环系统,并且可以耐受多种官能团。
