    摘要: Subject of the invention is a process for the production of L-carnitine, wherein a β-lactone, which is a 4-(halomethyl)oxetane-2-one, is converted into L-carnitine, wherein the process comprises an enzymatic conversion of the β-lactone into (R)-4-halo-3-hydroxybutyric acid or (R)-4-halo-3-hydroxybutyric acid ester.

    摘要: The invention relates to a method for the production of L-carnitine, wherein a β-lactone, which is a 4-(halomethyl)oxetane-2-one, is converted into carnitine with trimethylamine (TMA), wherein the β-lactone is not subjected to a basic hydrolysis step before being contacted with the trimethylamine. The invention also relates to a carnitine having a unique impurity profile.
