| 英文摘要 | A library of chiral zinc complexes formed in situ by the combination of achiral and racemic diimines with 3,3'-di(3,5-ditrifluoromethylphenyl)-binol and diethylzinc were evaluated in the asymmetric addition of diethylzine to n-acylimines. in the presence of 10 mol % of chiral ligand 4 and racemic diimine 5, high enantioselectivities of up to 97% ee and yields of up to 96% were achieved for a wide range of aromatic imines in dichloromethane at -30 degrees c.
