実験手順

Methyl (S)-2-methyl-3-phenylpropionate (5 mmol, 78.4% ee), a ruthenium complex 1 (0.01 mmol), and tetrahydrofuran (2 mL) were charged into a 100-mL autoclave equipped with a stirrer. Then, the mixture was subjected to hydrogenation at a hydrogen pressure of 5 MPa at 80° C. for 16 hours. The reaction liquid was analyzed by gas chromatography. As a result, (S)-2-methyl-3-phenylpropanol was obtained at a conversion rate of 99.0% and a selectivity of 98.6%. The obtained alcohol had an optical purity of 77.9% ee.
