Abstract

Alcohols Q 0230Organic-Inorganic Hybrid Materials for Enantioselective Organocatalysis. -Title agents based on amino acid exchanged clays are prepared. L-proline on montmorillonite and co-included ammonium cations are used as a model system for asymmetric aldol reactions between aromatic aldehydes and different ketones. The products are obtained with good yields and enantioselectivities. The catalyst can be recovered and reused without loss of activity after 10 cycles. -(SRIVASTAVA, V.; GAUBERT, K.; PUCHEAULT*, M.; VAULTIER, M.; ChemCatChem 1 (2009) 1, 94-98; Univ.
