Abstract:
A novel, recoverable C3-symmetric dendritic small molecular ligand (L1) containing BINOL has been synthesized to conduct the enantioselective addition of diethylzinc to aromatic aldehydes. The optically active secondary alcohols were obtained with up to 91% ee and up to 99% yield. After the reaction was finished, the dendritic ligand L1was recovered with a high yield by simple extraction and washing process. The recycled dendritic ligand was reused for five times without loss of catalytic activity as well as enantioselectivity. ©, 2015, Science Press. All right reserved.
