A simple and palladium-catalyzed procedure for synthesis of a novel series of potentially biologically active trifluoromethyl-substituted quinazolinones and N-arylquinazoline derivatives via condensation-cyclization reaction of 2-aminobenzamide, 2-amino-N′-arylbenzimidamides and 2-amino-N′-benzylbenzimidamides with trifluoroacetimidoyl chlorides has been developed. noteworthy, this investigation showed the possible of transition-metal-catalyzed activation of trifluoroacetimidoyl chlorides as a carbon trifluoromethylated source for the synthesis of quinazolines and quinazolinone derivatives in good to excellent yields.

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.
