An ortho-amination, ipso-C–H arylation mediated by palladium/norbornene cooperative catalysis is reported. This reaction proceeds through a sequential intermolecular C–N bond formation process followed by intramolecular C–H activation of a tethered arene. The products, aminated phenanthridinones, were generated in moderate to good yields. This method is also applicable to the formation of dibenzazepinones
Phenanthridinone derivatives have been prepared in good to high yields via palladium-catalyzed cyclization of readily available N-benzyl-N-benzoyl-o-iodoanilides.
