Yield | Reaction Conditions | Operation in experiment |
---|---|---|
93.69% | With water; sodium hydroxide; In methanol; at 15℃; for 12h;Inert atmosphere; | To a mixture of methyl (3R)-3-hydroxybutanoate (20 g) in methanol (133 mL) and H20 (67mL) was added NaOH (8.13 g) in one portion at 15°C under N2. The mixture was stirred at 15 °C for 12 h.The reaction mixture was concentrated under reduced pressure to give [(3R)-3- hydroxybutanoyl]oxysodium (20 g, 93.69percent yield) was obtained as a white solid. |
85% | With sodium hydroxide; In water; at 10 - 30℃; for 6h; | In a 500ml three-vial bottle,Methyl (R)-3-hydroxybutyrate (76.0 g) obtained in Example 1 was added and 300 ml of water was added.Control temperature is less than 30 °C,Sodium hydroxide (25.8 g) was slowly added in batches over 3 hours.Control temperature is not higher than 10 °C,After the addition, continue to react for 3 hours.Until the reaction is completed.Add 0.3g of activated carbon,Continue stirring for 0.5 hours,filter,The filtrate was concentrated to 100 ml,At this point, a large amount of solids precipitated.To room temperature,Stir and crystallize for 1 hour,Centrifugation,Vacuum dryingObtained 68.9 g of (R)-3-hydroxybutyrate as a white solid,Yield 85.0percent,The ee value is 91.5percent. |
