the enantioselectivity of these biohydrolyses strongly depends on the nature of the enzyme and of the substituent. Using some of these enzymes, this approach allows to prepare these epoxides in high optical purity. The potentiality to perform efficient preparative-scale resolution using such a biocatalyst was illustrated by the four-step synthesis of (S)-ibuprofen, a nonsteroidal antiinflammatory drug
使用来自不同来源的 10 种环氧化物水解酶研究了在芳环上不同取代的各种 α-甲基苯乙烯氧化物衍生物的生物水解。我们的结果表明,这些生物水解的对映选择性在很大程度上取决于酶和取代基的性质。使用这些酶中的一些,该方法允许以高光学纯度制备这些环氧化物。(S)-布洛芬是一种非甾体抗炎药和家用止痛药,是全球销量前十的药物之一,其四步合成说明了使用这种生物催化剂进行高效制备级拆分的潜力。使用组合化学酶促策略,
