A highly efficient, iron nitrate/TEMPO-catalyzed approach for the synthesis of quinazolinones has been achieved via a one-pot, tandem aerobic oxidative cyclization of primary alcohols with 2-aminobenzamides. This practical reaction tolerates a broad scope of substrates and could afford a variety of desirable products in good to excellent yields with air as the terminal green oxidant. Thus, the present synthetic protocol provides an efficient and concise strategy for the synthesis of quinazolinones.

KOtBu-BF3.OEt2 mediated synthesis of quinazolin-4(3H)-ones from 2-substituted amides with nitriles and aldehydes have been developed. In this protocol, a variety of nitriles as well as aldehydes react with 2-substituted benzamides to corresponding quinazolin-4(3H)-ones products in good to moderate yields, via the cleavage of C-X and C-N bonds and the formation of double C-N bonds simultaneously, in presence of potassium tert-butoxide.
Palladium-Catalyzed Oxidative Three-Component Coupling of Anthranilamides with Isocyanides and Arylboronic Acids: Access to 2,3-Disubstituted Quinazolinones

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