Author(s): Sharda Goel, Vijender Goel, Anju Bajwan

Herein a simple, efficient, versatile and convenient Hantzsch method for synthesis of 1,4-dihydropyridines using ethylacetoacetate, ammonium acetate and substituted arylaldehydes in the presence of Tetrabutylammonium Hydrogen Sulfate (TBAHS) have been reported. Among the popular reported heterogenous solid catalysts, TBAHS has gained high popularity in organic synthesis due to its selectivity, inertness and thermal stability. The method offers advantages such as good to better yields, short reaction times, a simple work-up procedure, easy isolation of catalyst and reusability of catalyst for several runs.
