has been expressed and characterized. CaADH enantioselectively reduces aromatic alpha-, beta- and gamma-keto esters to the corresponding D-hydroxy esters and provides a building block for the Taxotere side chain (95% yield, 95% de, 99% ee) by dynamic reductive kinetic resolution (DYRKR).
来自丙酮丁醇梭菌 (CaADH) 的 NADP 依赖性乙醇脱氢酶已得到表达和表征。 CaADH 对映选择性地将芳香族 α-、β- 和 γ-酮酯还原为相应的 D-羟基酯,并通过动态还原动力学拆分为泰索帝侧链提供构建模块(产率 95%,de 95%,ee 99%)(迪尔克)。
