摘要：
An efficient palladium-catalyzed protocol for the tandem synthesis of quinazolinone-fused phenanthridinones from 2-aryl-quinazolinones and o-dihaloarenes is described. This reaction sequence comprises direct intermolecular C-H arylation of 2-arylquinazolinones followed by an intramolecular aryl amidation reaction, affording 14Hquinazolino[3,2-f] phenanthridin-14-one derivatives in moderate to good yields.
