Siliceous mesocellular foam-supported chiral bisoxazoline: Application to asymmetric cyclopropanation

Chiral bisoxazolines were covalently immobilized onto siliceous mesocellular foams (MCF) by a simple method. The heterogenized bisoxazoline-copper catalysts showed high enantioselectivity (up to 85% enantiomeric excess (ee)) and excellent recyclability in asymmetric cyclopropanation reactions.
