摘要：
New Fréchet-type dendritic BINOL ligands bearing several BINOL units at the periphery have been successfully synthesized. The (dendritic BINOL) Ti(Ⅳ) complexes were proved to be efficient catalysts for the enantioselective addition of diethylzinc to aromatic aldehydes.Moreover,these ligands could be quantitatively recovered and reused at least five times without a loss of the yield and enantioselectivity.
