Abstract

A variety of Hantzsch 1-NH, 4-dihydropyridines were efficiently aromatized to the corresponding pyridine derivatives by treatment with HgO/I2 reagent in dichloromethane under mild and  heterogeneous conditions in good to excellent yields at room temperature. The products were separated by simple filtration and evaporation of the solvent.

KEYWORDS: HgO/I2, Hantzsch 1,4-dihydropyridine, aromatization, heterogeneous.
