Popis: 1, 4-Dihydropyridine derivatives have been obtained by MICHAEL condensation with cinnamylidene anilines 1 or N-p-tolyl-chalcone imine 5. With ethyl acetoacetate 1 and 5 yield 1-aryl-2-methyl-3-ethoxycarbonyl-4-phenyl-1, 4-dihydropyridines 2 and 6, with diethyl malonate 1-aryl-3-ethoxycarbonyl-2-oxo-4-phenyl-1, 2, 3, 4-tetrahydropyridines 7 and 8, and with acetyl acetone 1-aryl-2-methyl-3-acetyl-4-phenyl-1, 4-dihydropyridines 9 and 10.
