[Display omitted]
•The present method demonstrates a mild and one pot approach to the synthesis of 1,4-dihydropyridines.•A simple and efficient vitamin C catalyzed reaction was performed under microwave irradiation.•A number of substrates were generalized through the formation of products in good to excellent yields.•The plausible mechanism follows Hantzsch reaction between aromatic aldehydes and 1,3-dicarbonyl compounds.
A cost effective, operationally simple and environmentally benign one-pot access to 1,4-dihydropyridine (DHP) derivatives was achieved through the successful utilization of vitamin C as catalyst under microwave irradiation. The applicability of this method was fairly demonstrated through implementation of reaction conditions on diversified substrates. A plausible mechanistic interpretation for this reaction has been outlined based on Hantzsch reaction.
