The answer is in thermodynamics and kinetics.In a document type is Patent, and a compound is mentioned, 7331-52-4, (S)-4-Hydroxydihydrofuran-2(3H)-one, introducing its new discovery.
PROCESS FOR L-CARNITINE
The present invention relates to the process for the preparation of L-carnitine from racemic 3-acyloxy-gamma-butyrolactone or alkyl (R)-4-chloro-3-hydroxybutyrate. In more detail, this present invention relates to the process for the preparation of L-carnitine from (R)-3-hydroxy-gamma-butyrolactone, which was produced from racemic 3-acyloxy-gamma-butyrolactone by stereospecific hydrolysis using enzyme in the aqeous phase or organic phase including aqeous solvent or alkyl (R)-4-chloro-3-hydroxybutyrate, followed by a ring-opening reaction, epoxydation and a nucleophilic substitution by trimethylamine to prepare L-carnitine. The method of making L-carnitine is easier and more economical comparing to the con? ventional methods and L-carnitine produced has higher optical purity.
