Abstract

Abstract: A heterogeneous bifunctional catalyst was synthesized by incorporating chiral amine and acid groups into silica. This catalyst showed modest reactivity and enantioselectivity (up to 60%ee) for the direct asymmetric aldol reactions. It is suggested that the suitable incorporation between the amine and the acid groups in the bifunctional solid catalyst is crucial for the reactivity and the chiral induction of the reactions.

Key words: asymmetric catalysis, aldol reaction, bifunctional catalyst, inorganic-organic material
