biocatalytic methods for the stereoselective reduction of cyclic prochiral 1,3-diketones for the production of optically active β -hydroxyketones and/or 1,3-diols. The recombinant ketoreductase KRED1-Pglu (formulated as purified catalyst) and whole cells of wild type Escherichia coli DE3 Star were used as biocatalysts, displaying different and sometimes complementary stereoselectivity, thus allowing the preparation
摘要 我们开发了立体选择性还原环状前手性 1,3-二酮的生物催化方法,用于生产光学活性 β-羟基酮和/或 1,3-二醇。重组酮还原酶 KRED1-Pglu(配制为纯化催化剂)和野生型大肠杆菌 DE3 Star 的全细胞用作生物催化剂,显示出不同且有时互补的立体选择性,从而允许制备立体化学纯的 β-羟基酮(12-66% 分离)产率,> 99% ee)和 1,3-二醇(40–60% 分离产率,> 99% ee)。图形摘要
