ASYMMETRIC SYNTHESIS CATALYZED BY TRANSITION METAL COMPLEXES WITH CYCLIC CHIRAL LIGANDS |
| 摘要 |
PURPOSE: A Chiral phosphine ligand is provided to have a firm cyclic structure and to have a high selectivity of an enantiometric structure. CONSTITUTION: The present invention relates to rigid chiral ligands useful in making catalysts for asymmetric synthesis. More particularly, the present invention relates to new mono dentate and bidentate cyclic chiral phosphine ligands which are formed into catalysts to provide high selectivity of the enantiometric structure of the end-product. |
