The chiral third generation dendritic catalyst based on (1S,2R)-norephedrine could be readily recovered and reused in asymmetric transfer hydrogenation for acetophenone, and could be used three runs with the almost maintained enantioselectivities.

Key words: norephedrine, asymmetric transfer hydrogenation, recycling use, dendritic catalyst
