via β‐regioselective and S‐enantioselective ring‐opening of aryl epoxides with cyanate. Leveraging these engineered mutants, we developed a biocatalytic platform capable of synthesis of both chiral 4‐aryloxazolidinones (up to 47% yield, 98% ee, and 99% regioselectivity) and chiral 5‐aryloxazolidinones (up to 46% yield, >99% ee, and 98% regioselectivity). Furthermore, a collaborative approach utilizing
我们描述了卤代醇脱卤酶 HheG 的蛋白质工程,以增强其 R 对映选择性,通过芳基环氧化物与氰酸酯的 α 区域选择性开环合成手性 4-芳基恶唑烷酮。此外,我们实现了其区域选择性和对映选择性的反转,产生了一种 HheG 变体,专门用于通过芳基环氧化物与氰酸酯的 β-区域选择性和 S-对映选择性开环合成手性 5-芳基恶唑烷酮。利用这些工程突变体,我们开发了一个生物催化平台,能够合成手性 4-芳基恶唑烷酮(产率高达 47%、98% ee 和 99% 区域选择性)和手性 5-芳基恶唑烷酮(产率高达 46%、>99%) ee 和 98% 的区域选择性)。此外,利用两种区域选择性和对映选择性 HheG 突变体的协作方法已被证明能够同时合成手性 4-芳基恶唑烷酮和手性 5-芳基恶唑烷酮。

Synthesis of Chiral 5‐Aryl‐2‐oxazolidinones via Halohydrin Dehalogenase‐Catalyzed Enantio‐ and Regioselective Ring‐Opening of Styrene Oxides
enantio‐ and regioselective ring‐opening of styrene oxides with cyanate was developed by using the halohydrin dehalogenase HheC from Agrobacterium radiobacter AD1, generating the corresponding chiral 5‐aryl‐2‐oxazolidinones in up to 47% yield and 90% ee. Additionally, the origin of enantioselectivity and regioselectivity of the HheC‐catalyzed cyanate‐mediatedring‐opening process was uncovered by single
