SYNTHESIS OF 3-CYANO-4,6-DIARYL-3,4-DIHYDROPYRIDINE-2-THIONES

3-Cyano-4,6-diaryl-3,4-dihydropyridine-2-thiones have been synthesized for the first time by the condensation of arylideneacetophenones or 1-piperidino-1-phenyl-2-benzoylethane with cyanothioacetamide and the 1,1-dicyano-2-aryl-3-benzoylpropane with hydrogen sulfide in the presence of bases.It has been established by PMR spectroscopy that 3-cyano-3,4-dihydropyridine-2-thiones exist in solutions in the form of mixture of cis and trans isomers.
