THE INVESTIGATION OF CONVERTION OF BENZYLIDENEMALONONITRILES WITH ACETOACETANILIDE

By the Michael addition reaction of p-methyl,p-nitro substituted benzylidenemalononitriles and thio-phenylidenemalononitrile with acetoacetanilide pyridine derivatives were synthesized. Michael addition reaction was carried out for 2,6-dichlorobenzylidenema-lononitrile with acetoacetanilide and (E)-2-amino-4-(2,6-dichlo-rophenyl)-5-(1-hydroxyethylidene)-6-oxo-1-phenyl-1,4,5,6-tetra-hydropyridine-3-carbonitrile that is corresponding derivative of pyridine was obtained. Unlike V, VI and VII in this reaction the main product of this reaction is mainly in enol-form. Also the Michael addition reaction of p-trifluorobenzylidenemalononitrile and 2-chloro-5-nitrobenzylidenemalononitrile with acetoacetanilide has been investigated
