TETRABUTYLAMMONIUM HEXATUNGSTATE [TBA]2[W6O19]: A NOVEL HETEROGENEOUS CATALYST FOR ONE-POT SYNTHESIS OF HANTZSCH 1,4-DIHYDROPYRIDINES IN SOLVENT-FREE

A new method for one pot synthesis of Hantzsch 1,4-dihyropyridines was achieved by the reaction of aromatic aldehydes, ethyl acetoacetate and ammonium acetate at 80 °C in the presence of an isopoly tungstate ,tetrabutylammonium hexatungstate [TBA]2[W6O19], as an effective and environmentally friendl...
