Abstract

A palladium-catalyzed three-component reaction of isocyanides, 2,2,2-trifluoro-N-(2-iodophenyl)acetimidoyl chlorides, and amines for the one-pot synthesis of 2-(trifluoromethyl)quinazolin-4(3H)-imines was described. The protocol features a wide substrate scope, high efficiency, and readily available raw materials.
