Abstract
1,1-Dicyano-2,2-bis(trifluoromethyl)ethylene and 3,3-dicyano-2-(triflu oromethyl)acrylates react with primary arylamines in the presence of k etones to form 1,1-aryl-1,4-dihydropyridine derivatives under mild con ditions. The mechanism of this three-component reaction includes the f ormation of Schiff's bases as intermediates. 1,4-Dihydropyridine deriv atives, which are the products of three-component heterocyclization, w ere also obtained by reaction the corresponding Schiff's bases with 1, 1-dicyano-2-(trifluoromethyl)ethylenes.
