The invention relates to a process for preparing (S)-alpha-methylarylacetic acids from mixtures, such as racemic mixtures, of (R)-and (S)-alpha-methylarylacetic acid esters by enantiospecific hydrolysis using extracellular lipases of microbial origin (EC 3.1.1.3). Preferably S-2-(6-methoxy-2-naphthyl)-alpha-methylacetic acid is prepared (S-Naproxen).
该发明涉及一种从混合物中制备(S)-α-甲基芳基乙酸的过程,例如光学异构体混合物,通过使用微生物来源的胞外脂肪酶(EC 3.1.1.3)进行对映选择性水解。最好制备S-2-(6-甲氧基-2-萘基)-α-甲基乙酸(S-Naproxen)。
