Influence of Cofactor Regeneration Strategies on Preparative-Scale, Asymmetric Carbonyl Reductions by Engineered Escherichia coli
摘要:
This study was designed to determine whether whole cells or crude enzyme extracts are more effective for preparative-scale ketone reductions by dehydrogenases as well as learning which cofactor regeneration scheme is most effective. Based on results from three representative ketone substrates (an alpha-fluoro-beta-keto ester, a bis-trifluoromethylated acetophenone, and a symmetrical beta-diketone), our results demonstrate that several nicotinamide cofactor regeneration strategies can be applied to preparative-scale dehydrogenase-catalyzed reactions successfully.

Dynamicreductivekinetic resolution is applied toward the synthesis of α‐fluorinated‐β‐hydroxy esters using a set of commercially available ketoreductases. In many examples, the reactions are rapid (<1 h) and quantitative with high de and ee. 19F NMR spectroscopy proves useful for analysis of stereochemistry using in‐tube Mosher ester derivatization.
动态还原动力学拆分应用于使用一组可商购的酮还原酶合成α-氟代-β-羟基酯。在许多实例中,反应是快速的(<1小时),并且定量分析具有很高的de和ee值。19 F NMR光谱证明对使用管内Mosher酯衍生化的立体化学分析有用。
