Synthesis of 1,4-Dihydropyridines Using Ce(SO4)2-SiO2as Catalyst under Solvent-free Conditions

MIL-101-SO3H metal–organic framework as a Brønsted acid catalyst in Hantzsch reaction: an efficient and sustainable methodology for one-pot synthesis of 1,4-dihydropyridine

A straightforward and efficient methodology for the synthesis of the medicinally important 1,4-dihydropyridines has been demonstrated using MIL-101-SO₃H metal–organic framework as a sustainable Brønsted acid catalyst.

Alginic acid: a highly efficient renewable and heterogeneous biopolymeric catalyst for one-pot synthesis of the Hantzsch 1,4-dihydropyridines

Alginic acid was found to be an efficient, environmentally benign, easily recoverable and low-cost catalyst for clean synthesis of 1,4-dihydropiridine derivatives (DHPs).
