An enzymatic resolution process was developed to produce (S)-naproxen ester, (S)-naproxen or (S)-ibuprofen from the corresponding racemic thioesters by using lipase-catalyzedthiotransesterification or hydrolysis in organic solvents. Enzyme activity is greatly enhanced when activated naproxen thioesters containing an electron-withdrawing group are the substrates. Unlike other lipases, Candida rugosa
