Reaction Conditions

Reaction Steps

To a 100-mL autoclave were added 3-quinuclidinone (500 mg, 4.0 mmol), [RuCl(p-cymene)((R)-DM-SEGPHOS)]Cl (4.1 mg, 0.004 mmol), and (R)-DAIPEN (5.0 mg, 0.016 mmol). Under a nitrogen atmosphere, IPA (4 mL) and potassium t-butoxide/IPA solution (1.0 mol/L, 0.4 mL) were added thereto. Then, the mixture was stirred under a hydrogen pressure of 3 MPa at 30° C. for 15 hours. After analysis of the reaction solution, (R)-3-quinuclidinol was obtained at an optical purity of 90.8% ee and a conversion ratio of 99% or more.
