CATALYSTS FOR ASYMMETRIC SYNTHESIS CONTAINING RIGID CHIRAL LIGANDS |
摘要 |
This invention is to develop novel transition metal catalysts for the pratical 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. |
