Kinetic resolution of 2-mono- and 2,2-disubstituted epoxides was accomplished using epoxide hydrolases from bacterial and fungal origin by employing lyophilized whole microbial cells. In all cases investigated, the biocatalytic hydrolysis was shown to proceed with retention of configuration at the stereogenic center leading to 1,2-diols and remaining epoxides. The selectivity of the reaction was dependent
通过使用冻干的整个微生物细胞,使用来自细菌和真菌的环氧化物水解酶,可以完成2-单-和2,2-二取代的环氧化物的动力学拆分。在所研究的所有情况下,生物催化水解均显示在构型中心保留构型,从而导致1,2-二醇和剩余的环氧化物。反应的选择性取决于底物结构和所使用的应变,其E值范围从低或中等(使用2-单取代的环氧化物)到优异(E> 100,使用2,2-二取代的环氧乙烷)。
