以(1S,2R)-降麻黄碱为核心的第三代手性树状催化剂在对苯乙酮的不对称氢转移反应中可以方便的回收并循环使用. 该树状催化剂可以一共使用3次而保持对映选择性基本不变.

关键词: 降麻黄碱, 树状催化剂, 循环使用, 不对称氢转移反应

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
