Palladium-catalyzed intramolecular C–H arylation of 2-halo-<i>N</i>-Boc-<i>N</i>-arylbenzamides for the synthesis of N–H phenanthridinones
A palladium catalyzed synthesis of N–H phenanthridinones was developed via C–H arylation. The protocol gives phenanthridinones regioselectively by one-pot reaction without deprotection. It exhibits broad substrate scope and affords targets in up to 95% yields. Importantly, it could be applied for the less reactive o-chlorobenzamides.
