ChemInform Abstract: Cobalt Triflate Catalyzed One‐Pot Synthesis of Fluorophore 1,4‐Dihydropyridine Derivatives via Hantzsch Reaction.

Abstract A wide range of 1,4‐dihydropyridines (IV) are obtained by four‐component one‐pot condensation of aromatic aldehydes, β‐ketoesters, cyclic 1,3‐diones and ammonium acetate under mild reaction conditions.
