概要

• 論文の詳細を見る

• This work used Candida rugosa lipase to resolve racemic Naproxen by esterification with ethanol, n-butanol, n-hexanol or n-decanol in supercritical CO2. It was found that the lipase enantioselectively esterified (S)-Naproxen within all systems. The enantiomeric ratio increased four folds by slightly decreasing the alcohol concentration. The effect of the alcohol concentration on the enantioselectivity was greater than that of changing acyl acceptors.
