A simple, green and cost-effective protocol was achieved for the solvent free synthesis of 1,4-dihydropyridines catalyzed by AlCl(3) center dot 6H(2)O as a mild and effective catalyst at 60 degrees C in high yields. 1,4-Dihydropyridines thus formed were aromatized to pyridines by in situ generation of HOCl employing AlCl(3) center dot 6H(2)O/H(2)O(2)/H(2)O/EtOH as an excellent reagent system under domestic microwave irradiation (MWI). Both the synthesis and oxidation steps were efficiently accomplished in one-pot four-component fashion following the same protocol. (c) 2007 Elsevier B.V. All rights reserved.
