Practical Synthesis of Phenanthridinones by Palladium-Catalyzed One-Pot C-C and C-N Coupling Reaction: Extending the Substrate Scope to<i>o</i>-Chlorobenzamides
domino reaction proceeds through a sequential C–C and C–N bond-formation process in one pot. This protocol exhibits broad substratescope and affords a series of phenanthridinones in up to 93 % yield. Importantly, the protocol could also be applied for the less reactive o-chlorobenzamides. The approach constitutes the first example of the synthesis of phenanthridinones from this kind of substrate. Moreover
