Title:

ASYMMETRIC REACTION CATALYST AND PROCESS FOR PRODUCTION OF OPTICALLY ACTIVE COMPOUNDS WITH THE SAME

Document Type and Number:

WIPO Patent Application WO/2005/084803

Kind Code:

A1

Abstract:

[PROBLEMS] To provide an asymmetric reaction catalyst which is excellent in yield and stereoselectivity and easy of handling and a process for the production of optically active compounds with the same. [MEANS FOR SOLVING PROBLEMS] An asymmetric reaction catalyst obtained by mixing a pentavalent niobium compound with an optically active tri- or tetraol of (R)- or (S)-configuration having a binaphthol structure. The triol is represented by the general formula (I): (I) wherein Y is a divalent hydrocarbon group; and R¹ is hydrogen, halogeno, perfluoroalkyl having at most four carbon atoms, or alkyl or alkoxy having at most four carbon atoms.
