| 摘要 |
Optically active 2-sulfonyloxy-1-phenylethanol derivative of formula (II) can be prepared easily and selectively by the method of the present invention using an asymmetric reduction of an α-sulfonyloxy acetophenone compound with a rhodium catalyst having petamethylcyclopentadienyl group and a hydrogen donor, and the compound of formula (II) obtained in the inventive method exhibits a higher e.e. (enantiomer excess) value than that of the products in the conventional methods.
