| 英文摘要 | A series of C��-symmetric chiral ligands were developed and applied to catalytic asymmetric reactions leading to the formation of C-H and C-C bonds. High enantioselectivities in the hydrogenation of enamides (with and without the carboxylic acid), the addition of triethylaluminum to aldehydes, and conjugate addition of diethylzinc to enones have been achieved. The importance of the rigidity and the steric influence of the chiral ligand on the enantioselectivity of the catalyst were demonstrated. |
