摘要：
High activity and enantioselectivity were achieved in the rhodium-catalyzed asymmetric transfer-hydrogenation reactions of ketones in pure water using a novel amphiphilic block polypeptide ligand. The covalent linkage of the catalyst to the block copolymer plays a significant role and provides higher conversions and better recyclability than regular micellar or nonmicellar systems.
