(R)-(-)-3-HYDROXYBUTYRIC ACID, SODIUM SALT Usage And Synthesis

Chemical Properties	mp 165-167°C
Uses	chiral synthon
Uses	(R)-(-)-3-Hydroxybutyric acid sodium salt reacts with crown ether to form a supramolecular complex, which can catalyze the regioselective ring-opening polymerization of (S)-butyrolactone to form (R)-3-hydroxybutyrate oligomers (OHBs).
Uses	Optically active 3-hydroxybutyric acids are key intermediates of the biosynthesis and metabolism of fatty acids and exist widely in biological systems.
Synthesis	3976-69-0 13613-65-5 In a 500 mL three-necked flask, methyl (R)-3-hydroxybutyrate (76.0 g) made from Example 1 was added, followed by 300 mL of water. The reaction temperature was controlled to be below 30 °C, and sodium hydroxide (25.8 g) was added slowly in batches over a period of 3 hours. After addition, maintain the temperature no higher than 10°C and continue to stir the reaction for 3 hours until the reaction is complete. Add 0.3 g of activated carbon and filter after continuous stirring for 0.5 hours. The filtrate was concentrated to 100 mL, at which time a large amount of solid precipitated. Crystallization was stirred at room temperature for 1 hour, centrifuged and dried in vacuum to obtain 68.9 g of (R)-(-)-3-hydroxybutyric acid sodium salt as a white solid with a yield of 85.0% and an ee value of 91.5%.
