Abstract

The reaction of 2-amino-1,1,3-tricyanopropene (1) with acetylacetone and with salicylaldehyde gave the pyridine derivatives 2 and 9, respectively. Compounds 2 and 9 were transformed into pyridine derivatives 4 and pyrazolo[4,3-c]pyridine derivative 10 on treatment with hydrazines. 9 reacted with malononitrile and benzoylacetonitrile to give the pyrido[3,2-c]pyridine derivatives 11 and 12, respectively. The structures of the isolated products were established by the results of elemental analyses and IR and 1H NMR spectral data.
