1-aryl-2-chlorobut-2-en-1-ones. For the synthesis of these α-chloroenones, a two-step sequence was developed consisting of the allylation of the corresponding aldehyde with 3-dichloroprop-1-ene, followed by oxidation and further isomerization. The selective cooperative catalytic system involving ene-reductases (EREDs) and alcohol dehydrogenases (ADHs) afforded the desired optically active chlorohydrins under mild
设计并优化了双酶级联反应,从相应的 1-aryl-2-chlorobut-2-en-1-ones 开始获得对映体纯的氯代醇。对于这些 α-氯烯酮的合成,开发了一个两步序列,包括相应醛与 3-二氯丙-1-烯的烯丙基化,然后氧化和进一步异构化。涉及烯还原酶 (ERED) 和醇脱氢酶 (ADH) 的选择性协同催化系统在温和的反应条件下以优异的转化率(高达 >99%)和选择性(高达 >99:1 的非对映异构比)提供了所需的光学活性氯醇( dr), >99% 对映体过量 ( ee ))。
