(2E,2′E)-3,3′-(Propane-1,3-diyl)bis[oxy(4,1-phenylene)]bis[2-(4-aryl-1,3-thiazol-2-yl)acrylonitriles] and functionally substituted pyridines and fused pyrans containing a 3-[1,3-thi(selen)azol-2-yl]-substituent were synthesized by multicomponent condensations initiated by the Knoevenagel reaction. The structures of 2-amino-5-oxo-4-(1-phenylethyl)-4,5-dihydropyrano[3,2-c]chromene-3-carbonitrile and 2-amino-7-hexyloxy-4-cyclohexyl-4H-chromene-3-carborutrile were studied by X-ray diffraction analysis.
Transformation of 4-aryl(heteryl)-2,6-diamino-3,5-dicyano-4H-thiopyrans into substituted acrylonitriles, 1,4-dihydropyridines, 2,3,4,7- tetrahydrothiazolo[3,2-a]pyridine, and 4,7-dihydrothieno[2,3-b]pyridine

Cross-recyclization of 4-aryl(heteryl)-2,6-diamino-3,5-dicyano-4H- thiopyrans with α-bromoketones or alkyl halides formed substituted 3-aryl-2-(4-R-thiazol-2-yl)acrylonitriles, 2-alkylsulfanyl-1,4-dihydropyridines, 2,3,4,7-tetrahydrothiazolo[3,2-a]pyridin
