New synthetic approach to substituted 2-alkylsulfanyl-4,6-diaryl(heteryl)-1,4-dihydropyridine-, pyridine-, and thieno[2,3-b]pyridine-3-carbonitriles.

Abstract

Reactions of 1,3-diaryl(heteryl)prop-2-ene-1-thiones with 2-cyanoethanethio(seleno)-amides and alkyl halides led to the formation of substituted 2-alkylsulfanyl-4,6-diaryl(heteryl)-1,4-dihydropyridine-, pyridine-, and thieno[2,3-b]pyridine-3-carbonitriles.
