The onepot, three component reaction of p-hydroxy benzaldehyde, β-ketoester, and ammonium acetate afforded the corresponding monopodal 1,4-dihydropyridines as building blocks, which in turn converted into diversified novel bipodal, tripodal, and tetrapodal 1,4-dihydropyridines with different alkylating agents through conventional as well as microwaveassistedreactions. The unambiguous structural
