Abstract
New solid chiral auxiliaries are used in the enantioselective alkylation of benzaldehyde with diethylzinc. These auxiliaries are obtained by direct immobilization of their homogeneous counterparts, (-)-ephedrine and (-)-O-methyl-ephedrine. on the surface of mesoporous micelle templated silicates and aluminosilicates. Hybrid materials are characterized, and the interactions between the heteroatoms of the organic compounds and the surface are studied by FTIR spectroscopy. Efficiency of such hybrid solids is discussed.
