terpenones and bicyclic ketones, as well as kinetic resolution of racemic cycloketones. We demonstrated the applicability of the title enzymes in the enantioselective synthesis of (R)-(-)-Taniguchi lactone, a building block for the preparation of various natural product analogs such as ent-quinine. GRAPHICAL ABSTRACT:
摘要:这项研究调查了环烷酮单加氧酶和2-氧代-Delta3-4,5,5-三甲基环戊烯基乙酰辅酶A单加氧酶(一种最近被发现的Baeyer-Villiger单加氧酶家族的酶)的底物概况,该酶被用作全细胞生物催化剂。在分析规模上进行了多种酮的生物氧化:取代的前手性环丁酮和环己酮的不对称化,萜酮和双环酮的区域发散性氧化以及外消旋环酮的动力学拆分。我们证明了标题酶在(R)-(-)-谷口内酯的对映选择性合成中的适用性,这是制备各种天然产物类似物如对苯二酚的基础。图形概要:
