Chiral Metal-Organic Assemblies-A New Approach to Immobilizing Homogeneous Asymmetric Catalysts

摘要

Homogeneous asymmetric catalysis has the advantages of high enantiose-lectivity and catalytic activity for a variety of asymmetric transformations conducted under relatively mild reaction conditions.However,since the catalyst loadings employed in most cases have ranged from 1 to 10 mol%,homogeneous methods remain impractical due to the high cost of the chiral noble metal catalysts and the difficulty of their recovery and reuse.
