Herein, we describe the direct synthesis of quinazolinones via cross-dehydrogenative coupling between methyl arenes and anthranilamides. The C-H functionalization of the benzylic sp3 carbon is achieved by di-t-butyl peroxide under air, and the subsequent amination-aerobic oxidation process completes the annulation process. Iron catalyzed the whole reaction process and various kinds of functional groups were tolerated under the reaction conditions, providing 31 examples of 2-aryl quinazolinones using methyl arene derivatives in yields of 57-95percent. The synthetic potential has been demonstrated by the additional synthesis of aryl-containing heterocycles. This journal is

We have developed two different approaches in parallel to rapidly access 2,4-bis aminoaryl pyridine compounds from a common starting material. The C-4/C-2 approach uses palladium-mediated coupling reactions to sequentially functionalize C-4 and then C-2. An alternative C-2/C-4 route uses a regioselective SNAr reaction to first substitute at C-2 then subsequently at C-4 by a palladium-mediated reaction. Both approaches have been used successfully to provide a range of 2,4-bis-aminoaryl pyridine compounds.
