Abstract

magnified image An easy, safe, effective and handy method for oxidative aromatization of Hantzsch 1,4‐dihydropyridines catalyzed by hypervalent iodine (iodosobenzene) and potassium bromide to corresponding pyridine derivatives in high‐yields and within short span of time was described. Dealkylation in case of 4‐n‐alkyl substituted 1,4‐dihydropyridines was not obtained. J. Heterocyclic Chem., (2010).
