    Abstract: The present invention is concerned with a process of preparing (R)-lacosamide. The process comprises providing an (R,S)-lacosamide precursor and contacting the same with at least an enzyme in the presence of a solvent. The enzyme either stereoselectively hydrolyzes or acetylates an (R)- or (S)-enantiomer of the (R,S)-lacosamide precursor. The process further comprises where appropriate also concurrently, or successively, employing one or more reagents capable of converting the hydrolysed or acetylated (R)- or (S)-enantiomer to (R)- lacosamide.

    Abstract: With known methods of racemizing N-acetyl-D(L)- alpha -aminocarboxylic acids in the non-aqueous state by heating them to temperatures above room temperature, significant quantities of by-products are formed, especially acetyl dipeptides. By converting at least a proportion of the N-acetyl-D(L)- alpha -aminocarboxylic acids to corresponding N-acetyl-D(L)- alpha -aminocarboxylic acid salts before or during the heating, it is possible to increase the sojourn time of the educt which is to be racemized at higher temperatures without any evident increase in the quantity of by-product formed (in particular acetylated dipeptides). Also disclosed is the production of optically active amino acids by enzymatic splitting of racemic compounds.
