1,1-Dicyano-2,2-bis(trifluoromethyl)ethylene and 3,3-dicyano-2-(trifluoromethyl)acrylates react with primary arylamines in the presence of ketones to form 1,1-aryl-1,4-dihydropyridine derivatives under mild conditions. The mechanism of this three-component reaction includes the formation of Schiff's bases as intermediates. 1,4-Dihydropyridine derivatives, which are the products of three-component heterocyclization, were also obtained by reaction the corresponding Schiff's bases with 1,1-dicyano-2-(trifluoromethyl)ethylenes.
