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‐mediated ring‐opening process was uncovered by single
利用土壤杆菌放射杆菌AD1的卤代醇脱卤酶HheC,开发了一种有效的生物催化方法,用于对苯乙烯氧化物与氰酸酯的对映和区域选择性开环,生成相应的手性5-芳基-2-恶唑烷酮,产率高达47%,产率为90% ee。此外,单个对映异构体的生物转化和分子对接研究未发现HheC催化的氰酸酯介导的开环过程的对映选择性和区域选择性的起源。
