Flipping the Substrate Creates a Highly Selective Halohydrin Dehalogenase for the Synthesis of Chiral 4-Aryl-2-oxazolidinones from Readily Available Epoxides
Chiraloxazolidinones are a class of important heterocyclic compounds in pharmaceutical chemistry due to their biological activity. Halohydrin dehalogenase-catalyzed epoxide ring-opening reaction with cyanate offers an attractive approach to the synthesis of chiraloxazolidinones, but the α/β-regioselectivity and stereoselectivity are still un-addressed issues. In this study, a unique halohydrin dehalogenase
手性恶唑烷酮类化合物因其生物活性而成为药物化学中一类重要的杂环化合物。卤代醇脱卤酶催化的环氧化物与氰酸酯的开环反应为合成手性恶唑烷酮提供了一种有吸引力的方法,但 α/β-区域选择性和立体选择性仍然是未解决的问题。在这项研究中,发现一种独特的卤代醇脱卤素酶 ( Ab HheG) 对外消旋氧化苯乙烯与氰酸盐的开环具有高活性和 α/β-区域选择性,但立体选择性较差 ( E < 3)。通过重塑Ab HheG的底物结合位点,获得了具有优异 α/β-区域选择性和立体选择性的变体 Y15M/N182S。变体显示E> 200 对于 13 种测试的氧化苯乙烯中的 9 种。由于 ( R )-4-aryl-2-oxazolidinones 很容易与 ( R )-styrene oxides 分离,因此 ( R )- 和 ( S )-4-aryl-2-oxazolidinones 都可以很容易地制备。晶体学和酶-
