Abstract

An efficient oxidative aromatization of Hantzsch 1,4-dihydropyridines and 1,3,5-trisubstituted pyrazolines to the corresponding pyridines and pyrazoles has been reported using Zr(NO3)4 in acetic acid at ambient temperature. The reactions are very fast and the products were isolated in high yields and in pure form.
