Abstract

Palladium-catalyzed [4+2] annulation of aryl and alkenyl carboxamides with 1,3-dienes via C–H functionalization is developed using air as the terminal oxidant. The method demonstrates good functional group tolerance and high stereoselectivity, affording a series of 3,4-dihydroisoquinolones and 5,6-dihydropyridinones in yields of up to 99%.
