Silicagel Supported Ferric Chloride (SiO2-FeCl3)
|Abstract:||A simple and efficient method for the synthesis of 6-aryl-9-(4-hydroxy-3-ethoxyphenyl)-1,2,4-triazolo[4,3-a][1,8] naphthyridines 4 by the oxidation of the corresponding ethylvanillin 3-aryl-1,8-naphthyridin-2-ylhydrazones 3 using silicagel supported ferric chloride (SiO2-FeCl3) in solvent-free conditions under microwave irradiation has been described. The products are obtained in good yields and in a state of high purity. The structural assignment of compounds 3 and 4 were based on their elemental analyses and spectral data.|
