A novel approach for the synthesis of 2,3-diarylquinazolinones using iron as catalyst is described. Various 2-nitro-N-arylbenzamides reacted with benzylic alcohols to selectively give the corresponding products in the absence of external oxidant or reductant.

A novel palladium-catalyzedoxidative three-component coupling of easily accessible N-substituted anthranilamides with isocyanides and arylboronicacids is achieved. This protocol offers an alternative approach toward 2,3-disubstituted quinazolinones with a wide substrate scope and good functional group tolerance.
