Synthesis and Spectral Characterization of Some New 4-(2,6-Diarylpyridin-4-yl)-2H-chromen-2-ones

Some new 4-(2,6-diarylpyridin-4-yl)-2H-chromen-2-one derivatives 5a-l have been synthesized by reacting 4-(3-oxo-3-arylprop-1-enyl)-2H-chromen-2-ones 3a-c with appropriate 1-(2-oxo-2-arylethyl)pyridinium bromide salt 4a-d in the presence of ammonium acetate in refluxing glacial acetic acid. The newl...

Summary:Some new 4-(2,6-diarylpyridin-4-yl)-2H-chromen-2-one derivatives 5a-l have been synthesized by reacting 4-(3-oxo-3-arylprop-1-enyl)-2H-chromen-2-ones 3a-c with appropriate 1-(2-oxo-2-arylethyl)pyridinium bromide salt 4a-d in the presence of ammonium acetate in refluxing glacial acetic acid. The newly synthesized compounds have been characterized by elemental and spectral analysis.
