| titleOfInvention | A kind of cinchona base ligand and its preparation method and application |
| abstract | The invention belongs to the field of organic chemical ligands, specifically a cinchona base ligand, which has the structure of general formula I or its tautomers, enantiomers, and diastereoisomers: Wherein, R 1 is selected from alkyl, alkenyl, -CH=CHPh, R 2 is selected from hydrogen, alkyl, phenyl, substituted phenyl, R is selected from substituted phenyl. The invention also discloses the preparation method and application of the cinchona base ligand. The ligand of the present invention has advantages in both stereoselectivity and reaction efficiency, and can obtain higher ee value and yield in asymmetric reactions. |
