Synthesis of Novel 4-1-(3-Chlorophenyl)-3-(pyren-1-yl)-1H-pyrazol-4-yl-6-(substituted phenyl)-1,2-dihydro-2-oxo(imino)pyridine-3-carbonitriles

摘要

A novel compounds of 4,6-diaryl-2-oxo(imino)-1,2-dihydro-pyridine-3-carbonitriles has been synthesized by reaction of 1-(3-chlorophenyl)-3-(pyren-1-yl)-1H-pyrazole-4-carbaldehyde with different 1-(substituted phenyl)ethanones and ethyl cyanoacetate or malononitrile in presence of ammonium acetate. Structure of the newly synthesized compounds was elucidated from chemical and spectroscopic data.
