Abstract

Novel chalcones were synthesized by Aldol condensation of aromatic aldehydes and the hitherto not described 3-(2,5-dimethoxyphenyl)-3-oxopropanenitrile in basic medium followed by cyclization with malononitrile to corresponding pyran derivatives. The well characterized pyran derivatives were further transformed into pyridine derivatives by neat heating with ammonium acetate. The fluorescence properties and quantum yield of these synthesized compounds were studied.
