Synthesis and alkylation of n(3)-aryl-n(5)-phenyl-6-amino-4-aryl(2-furyl)-2-thioxo-1,2,3,4-tetrahydropyridine-3,5-dicarboxamide

N₍₃₎-Aryl-N₍₅₎-phenyl-6-amino-4-aryl(2-furyl)-2-thioxo-1,2,3,4-tetrahydropyridine-3,5-dicarboxamides have been obtained by the interaction of N-phenyl-3-aryl(2-furyl)-2-cyanoacrylamides with 3-amino-3-thioxopropananilides under the conditions of the Michael reaction. N₍₃₎-Aryl-N₍₅₎-phenyl-2-alkylthio-6-amino-4-aryl(2-furyl)-3,4-dihydropyridine-3,5-dicarboxamides and N₍₃₎, N₍₅₎-diphenyl-6-benzylthio-4-(2-furyl)-2-oxo-1,2,3,4-tetrahydropyridine-3,5-dicarboxamides were synthesized by alkylation of the products. __________ Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 7, pp. 1018–1023, July, 2008.
