实验步骤: Chiral hydrogenation of (E)-3-nonene-2-one was carried out(see formula (14) below). That is, a reaction was carried out in accordance with the procedures of Example 4 using the (S,SS)-ruthenium hydride complex (1.5 mg; 0.00125 mmol) synthesized in Example 2 and using (E)-3-nonene-2-one (701 mg; 5.0 mmol) (made by Tokyo Kasei Kogyo Co., Ltd.)as the substrate and 2-propanol (2.5 mL) as the solvent. However, the hydrogen pressure was set to 8 atmosphere, the reaction temperature was set to 25° C., and the reaction time was set to 16 hours. As a result, (E)-3-nonene-2-ol was obtained at a GC yield of 95%, isolation yield of 93% (668 mg; 4.65 mmol), and enantiomeric excess of 99%. GC (column: Chirasil-DEX CB; column temperature: 65° C.; injection and detection temperature: 200° C.; helium pressure: 41 kPa; tR of (R)-(E)-3-nonene-2-ol: 70.5 minutes(99.6%); tR of (S)-(E)-3-nonene-2-ol:80.7 minutes (0.4%)); [α]26D+21.16° (c:1.042; CHCl3); absolute structure: R; literature value: [α]25D+10.68° (c:1.03; CHCl3), 97% ee (R). synthesized in Example 2 was set to 25° C.
