Abstract
Abstract Optically active norephedrine was anchored on MCM-41 silica material. The insoluble system was utilized as an enantioselective ligand in the asymmetric transfer hydrogenation of ketones. This reaction provided ( R )-secondary alcohols with satisfactory enantioselectivities (up to 95% ee) in good conversion. The results are comparable to those of the analogous homogeneous counterpart.
