Description
Technical field
The present invention relates to a kind of chirality diene ligand and synthetic method thereof of novel texture, these chirality diene ligands can be applied in the asymmetric reaction.
Background technology
The alkene metallic compound is used in transition metal-catalyzed reaction in a large number, but the binding ratio that all the time it is believed that alkene and metal a little less than, therefore be as the occupy-place molecule with it, be used for carrying out the ligand exchange synthetic catalyst, and it does not used as part necessary in the transition-metal catalysis with other heteroatom ligands.But studies show that successively, alkene metal complex itself is catalysis transition metal reaction well just, especially cyclooctadiene (COD) metal complex can successfully apply in a lot of catalyzed reactions, people recognize that gradually the part that alkene can be used as in the reaction equally uses ((a) Brown thus, J.M.and Lloyd-jones, G.C.J.Chem.Soc.Chem.Commun.1992,710.
