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.
本发明涉及制备(R)-拉科莎胺的方法。该方法包括提供(R,S)-拉科莎胺前体,并在溶剂存在下与至少一种酶接触。该酶可以对(R,S)-拉科莎胺前体的(R)-或(S)-对映体进行立体选择性
水解或乙酰化。该方法进一步包括,在适当的情况下,同时或依次使用一种或多种能够将
水解或乙酰化的(R)-或(S)-对映体转化为(R)-拉科莎胺的试剂。
