significant 2,3‐dihydroquinazolin‐4(1H)‐ones has been disclosed. The one‐pot multicomponent reaction was performed through a palladium‐catalyzed ortho‐selective oxidative carbonylation of N‐substituted anilines with CO and primary amines, and subsequent condensation with aldehydes in MeCN by using alkylamino as the directing group, KI/AcOH as the additives, and Cu(OAc)2 as the oxidant. This intriguing
