enantioselective hydrolysis of dicarboxylic acid monoesters was investigated. The racemic substrates, which were prepared by coupling of the corresponding alcohols with dicarboxylic anhydrides, were enantioselectively hydrolyzed by lipase from Candida antarctica (Novozym 435) in a buffer at 30 °C. The products were easily separated by a simple extraction procedure without laborious column chromatography
研究了酶介导的二羧酸单酯的高对映选择性水解。通过将相应的醇与二羧酸酐偶联制备的外消旋底物在30°C的缓冲液中被南极假丝酵母(Novozym 435)的脂肪酶对映体选择性水解。可以通过简单的提取方法容易地分离产物,而无需费力的柱色谱,得到两种醇的对映异构体。然后,我们确定二羧酸单酯是制备光学活性醇的合适替代底物。
