Argon-degassed methanol (2 mL) was added and the mixture was stirred for 15 minutes. Methyl propionylacetate (63 μL; 0.5 mmol) dissolved in 2 mL of argon-degassed methanol was added and was washed in with 1.0 mL of argon-degassed methanol. The reaction mixture was pressurized with argon and vented five times and then pressurized to 20.7 barg (300 psig) with hydrogen and stirred at ambient temperature for 6 hours. The vessel was vented, then pressurized with argon and vented five times, and the solution was assayed by chiral GC to indicate 100% conversion to methyl (S)-3-hydroxypentanoate with 86.2% ee.

With hydrogen;dichloro(benzene)ruthenium(II) dimer; (11bS,11'bS)-4,4'-(9,9-dimethyl-9H-xanthene-4,5-diyl)-bis-dinaphtha[2,1-d:1',2'-f][1,3,2]dioxaphosphepin; In ethanol; dichloromethane; at 60℃; under 45004.5 Torr; for 20h;Product distribution / selectivity; [Ru(benzene)Cl2]2 (N) (16 mg, 0.032 mmol) and a diphosphonite (0.067 mmol) were introduced into a 25 ml Schlenk tube. The tube was purged three times with argon before dry dimethylformamide (DMF) (3 ml) was added. The resulting mixture was heated to 100 C. for 30 minutes and then cooled to 60 C. The solvent was removed under reduced pressure, and the catalyst was obtained as a pale green-yellow solid. This catalyst was dissolved in dry dichloromethane (8 ml) and distributed uniformly between 8 vials (in each case 1 ml), which had already been purged three times with argon. A ketone, such as a β-keto ester (III) (0.8 mmol), was introduced into each vessel, then in each case 3 ml of ethanol were added. These were then transferred to a high-pressure autoclave. Once it had been purged three times with H2, the autoclave was adjusted to a pressure 60 bar with H2, and the reactions were stirred magnetically at 60 C. over 20 h. The autoclave was subsequently cooled to room temperature and H2 was cautiously discharged. Samples were taken from each reaction solution and put through a small amount of silica gel before the GC analysis in order to determine the conversions and ee values. The absolute configuration was determined in comparison to known compounds described in the literature.

With dichloro[(S)-(-)-2,2'-bis(diphenylphosphino)-1,1'-binaphthyl]ruthenium(II); hydrogen; In methanol; at 100℃; under 3800.26 Torr; for 48h; Synthesis of 1-Azido-3-Pentanol (31) (Scheme 14) A solution of methyl-3-oxo-pentanoate (31) (20 g) noyori hydrogenation with RuCl2 [(S)-BINAP] (60 mg), in methanol was added. The flask was charged with hydrogen gas (5 atm) at 100 C. The resulting suspension was vigorously stirred for 48 hours. The reaction mixture was diluted with methanol and the combined organic layers were filtered through a Celite pad. The combined organic phases were evaporated in a rotary evaporator to yield the product (S) isomer of methyl-3-hydroxy-pentanoate (32). The methyl-3-hydroxy-pentanoate (secondary alcohol-32) was protected with TBDMSCl in the presence of imidazole in dichloro methane. The reaction mixture was stirred for 24 hours at room temperature. This reaction was quenched with aqueous saturated sodium bicarbonate and extracted with dichloro methane. The combined organic phases were dried over Na2SO4 and the combined organic phases were evaporated in a rotary evaporator to yield the TBS protected product (33). A stirred solution of ester was reduced with di-isobutyl aluminum hydride in dichloro methane at -78 C. for 5 hours. This reaction mixture was quenched with saturated aqueous sodium potassium tartarate. The combined organic and aqueous layers were filtered and organic layer was separated by separating funnel. The aqueous layer was extracted with dichloro methane. The combined organic phases were dried over Na2SO4 and the combined organic phases were evaporated in a rotary evaporator to yield the product primary alcohol (34) as a pale yellow liquid. The primary alcohol was protected with methane sulfonyl chloride in the presence of TEA in dichloromethane. The reaction mixture was stirred for 4 hours at 0 C. This reaction was quenched with aqueous saturated sodium bicarbonate and extracted with dichloro methane. The combined organic phases were dried over Na2SO4 and the combined organic phases were evaporated in a rotary evaporator to yield the methane sulfonyl protected product (35). The methane sulfonyl protected primary alcohol was stirred at 70 C. with NaN3 in DMF for 16 hours. A stirred solution of TBS protected secondary alcohol. This reaction was quenched with pre cooled ice water and extracted with diethyl ether. The combined organic phases were dried over Na2SO4. The combined organic phases were evaporated in a rotary evaporator to yield the azido product as a colorless liquid (36). This was deprotected with TBAF in tetrahydrofuran at room temperature. This reaction was quenched with saturated ammonium chloride solution and extracted with diethyl ether; the combined organic phases were dried over Na2SO4 and evaporated on rotary evaporator to yield the product 1-azido-3-pentanol (36A) as a colorless liquid.
> 99.5%Chromat. With hydrogen; In isopropyl alcohol; at 50℃; under 30003 Torr; for 10h;Autoclave; Glovebox; General procedure: As a typical run for asymmetric hydrogenation of β-keto esters, 0.026 g Ru/5-BINAPPOPs-1 catalyst, 0.20 g methyl acetoacetate, and 2 mL of isopropanol (ipro) were added to a 30-mL autoclave in a glove box. After the reactor was purged with H2 four times, its pressure was finally adjusted to the desired value, heated from room temperature to the reaction temperature of 50 C, and stirred for 10 h. The catalyst was separated by centrifugation, and the product was analysed using gas chromatography (GC; Agilent 7890B gas chromatograph equipped with a flame ionization detector and a Cyclosil-B capillary column).
