The present invention provides an asymmetric reduction catalyst effective in preparing optically-active alcohol compounds having various functional groups, and a process for preparing optically-active alcohol compounds using said asymmetric reduction catalyst.
The organic metal compound of the present invention is represented by the following general formula (1):
wherein R
1
and R
2
may be mutually identical or different, and are an alkyl group, a phenyl group, a naphthyl group, a cycloalkyl group, or an alicyclic ring formed by binding R
1
and R
2
, which may have a substituent; R
3
is a hydrogen atom or an alkyl group; Cp is a cyclopentadienyl group, which may have a substituent, bound to M
1
via a π bond; X
1
is a halogen atom or a hydrido group; M
1
is rhodium or iridium; and * denotes asymmetric carbon.
