title: Oxidative aromatization of Hantzsch 1,4-dihydropyridines in the presence of mixed-addenda vanadomolybdophosphate heteropolyacid, H6PMo9V3O40.
abstract: A variety of Hantzsch 1,4-dihydropyridines were oxidized to the corresponding pyridines in high yields in the presence of H(6)PMo(9)V(3)O(40), a Keggin type heteropolyacid, in refluxing acetic acid. The heteropolyacid was found to be reusable.
