(2E,2E)-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.
