标题:Asymmetric synthesis catalyzed by transition metal complexes with rigid chiral ligands
发明人：ZHANG XUMU
权利人:PENN STATE RES FOUND
摘要:This invention is to develop novel transition metal catalysts for the practical synthesis of important chiral molecules. The invention emphasizes asymmetric catalysis based on chiral bidentate phosphine ligands with cyclic ring structures which could be used to restrict conformational flexibility of the ligands and thus the efficiency of chiral transfer can be enhanced through the ligand rigidity.
