Abstract: | A green and efficient method for direct preparation of 3-cyanopyridine from aromatic aldehydes is reported. A series of novel 4-aryl-2-amino-6-(naphthalene-1-yl)-3-cyanopyridine derivates were successfully prepared by one-pot synthesis of three-component domino reactions including aromatic aldehydes, 1-acetylnaphthalene, and dicyanomethane in the presence of ammonium acetate in a solution of ethanol under microwave irradiation. This synthetic method for these compounds possesses many advantages including greater yield and shorter reaction times compared with traditional methods. The structures of these compounds were confirmed by means of high-resolution mass spectrometry, 1H NMR, 13C NMR, and infrared. Moreover, the results of their fluorescent spectra showed that these compounds have good fluorescence intensity excited by the visible light wavelength of 416 nm. |
