Chiral copper proline diamide complex has been immobilized on surface of mesoporous silica. These heterogenized complex catalysts were examined as asymmetric catalysts for the epoxidation of alpha,beta-unsaturated carbonyl compounds with hydrogen peroxide, tert-butyl hydroperoxide and urea hydroperoxide as the oxidants under solvent-free condition. Enantiomeric excesses of up to 84% can be achieved conveniently with a good conversion using these promising catalysts.
