Asymmetric Reaction Catalyst and Method for Preparing Optically Active Compound Using the Same |
摘要 |
An asymmetric reaction catalyst is obtained by mixing a pentavalent niobium compound and an optically active triol or tetraol having a binaphthol structure of R or S configuration, and the triol is represented by the following formula: (wherein, Y is divalent hydrocarbon and R<SUP>1 </SUP>is a hydrogen atom, a halogen atom, a trifluoromethyl group, or an alkyl group or alkoxy group having at most 4 carbons).
