A mild procedure for the diastereoselective Diels-Alder reaction of methyl acrylate and cyclopentadiene was performed using modified silica with different concentrations of metal ions as Lewis acid support. According to the results, among the tested metal ions, cadmium ion supported on the silica was the best diastereoselective catalyst in this reaction.
