A procedure on palladium-catalyzed carbonylative reaction of trifluoroacetimidoyl chlorides and nitro compounds for the construction of pharmaceutically valuable 2-(trifluoromethyl)quinazolin-4(3H)-ones has been achieved. In this transformation, Mo(CO)6 has been used both as a convenient CO source and a reducing reagent. This newly developed protocol is compatible with various nitro compounds and can be readily scaled up to 1 mmol scale. (Figure presented.).
FeCl3-Mediated Synthesis of 2-(Trifluoromethyl)quinazolin-4(3 H)-ones from Isatins and Trifluoroacetimidoyl Chlorides

An FeCl3-mediated cascade coupling/decarbonylative annulation reaction for the efficient construction of 2-(trifluoromethyl)quinazolin-4(3H)-ones has been developed. This transformation employs readily available isatins and trifluoroacetimidoyl chlorides as the starting materials, providing a facile and practical route to diverse biologically relevant quinazolin-4(3H)-one derivatives. A plausible reaction pathway has been proposed based on the mechanistic observations.
