Reactions of cyclic enhydrazinoketones with arylidene derivatives of malononitrile. Synthesis of fused N-substituted 1,4-dihydropyridines

Article abstract of DOI:10.1007/BF02495769

A new method for the synthesis of fused N-amino-1,4-dihydropyridines was proposed. The method is based on the addition of cyclic enhydrazinoketones to arylidenemalononitriles. The structures of the compounds synthesized were studied using ¹H NMR spectroscopy.
