Description	Synthesis of 1,4-dihydropyridines via a four component one pot reaction starting from alpha,beta-unsaturated aldehyde, beta-keto ester, amine and alcohol, catalysed by SO42-/CexZr1-xO2 is explored. The method has several advantages such as reusability of catalyst, avoidance of a multistep procedure and readily available starting materials. The protocol gives high to moderate yields for structurally diverse amines, beta-keto esters and alpha,beta-unsaturated aldehydes. SO42-/CexZr1-xO2 (x = 0.02-0.15 mol%) catalysts were prepared and characterized by various analytical techniques such as XRD, FT-IR, TGA-DSC, SEM-EDAX and the total acidity.
