During the past several years, the field of electro optical organic and nonlinear optical material has received extensive attention [1-3] because of their possible application as fluorescence probes, electro optical switches and chemical sensors. Due to the electron donating and accepting groups on opposite sides, such material, which is connected by a highly delocalized electron system, is imp...

Synthesis of 4-(N,N- dimethylamino)-3-aryl-3-butene-2-one, ethyl-5-aryl-4-oxo-4H-pyran-2-carboxylate, ethyl-5-aryl-4-pyridones-2-carboxylate and 5-aryl-3-cyano-5-methyl-2-pyridones (aryl=3-thienyl, 2-furyl) are described.
