The condensation of ethyl arylideneacetoacetate with cyanothioacetamide and of arylidenecyanothioacetamides with ethyl acetoacetate or of arylidenecyanothioacetamides with ethyl β-aminocrotonate gave 3-cyano-4-aryl-5-ethoxycarbonyl-6-methyl-3,4-dihydropyridine-2-thiones.PMR spectroscopy showed that the 3-cyano-4-aryl-3,4-dihydropyridine-2-thiones are formed as a mixture of cis and trans isomers.
