| titleOfInvention | Method of preparing R-(+)-alpha-lipoic acid and its salt |
| abstract | The present invention discloses a method for preparing R-(+)-LA as well as its metal salts including sodium salt, potassium salt, calcium salt, magnesium salt, zinc salt, ferric salt, cooper salt , lithium salt and its organic salt, wherein a racemic Ethyl 6, 8-Dichlorooctanoic acid is employed as starting agents, followed by a hydrolysis and resolution processes to obtain (+)DCA, and then through sulfuration and cyclization process to obtain R-(+)-LA as well as its varied salts. A method for converting the (−)DCA to (+)DCA is also introduced. |
