Abstract
A method for producing 1,3-cyclohexanediol compounds, particularly a 1,3-cyclohexanediol compound rich in cis-form. A 1,3-cyclohexanediol compound is reduced with a boron hydride compound such as sodium borohydride. Selectivity of cis-form is improved when an alkali metal compound and/or an alkaline earth metal compound, particularly a halide, is allowed to exist in the reaction system.
Claims4
A method for producing a 1,3-cyclohexanediol compound represented by the following general formula (2), which comprises reducing a 1,3-cyclohexanedione compound represented by the following general formula (1) with a boron hydride compound:
- 5
- (wherein R1, R2, R3 and R4 each independently represents hydrogen atom, a halogen atom, an alkoxycarbonyl group, an alkyl group which may have one or more substituent(s), an alkoxy group which may have one or more substituent(s) or phenyl group which may have one or more substituent(s))
- 6
- (wherein R1, R2, R3 and R4 are as defined in the formula (1)).
