A series of enantioenriched (hetero)aromatic secondary allylic alcohols has been synthesized through deracemization of the corresponding racemic mixtures combining a non-selective chemoenzymatic oxidation (laccase from Trametes versicolor and oxy-radical TEMPO) and a stereoselective biocatalyzed reduction (lyophilized cells of E. coli overexpressing an alcohol dehydrogenase, ADH). Both steps were performed in aqueous medium under very mild reaction conditions. After optimization, a sequential one-pot two-step protocol was set up, obtaining the corresponding chiral alcohols in moderate to high conversions (48–95%) and enantiomeric excess (65->99% ee). Depending on the ADH stereopreference, both antipodes from these valuable chiral synthons could be prepared, even at preparative scale (119−178 mg), in a straightforward manner.

通过将相应的外消旋混合物脱除油，合成了一系列对映体富集的（杂）芳族仲烯丙醇，结合了非选择性化学酶氧化（来自Trametes versicolor和氧自由基TEMPO的漆酶）和立体选择性生物催化还原（E.冻干细胞）。大肠杆菌过表达酒精脱氢酶（ADH）。这两个步骤均在水性介质中在非常温和的反应条件下进行。优化后，建立了一个顺序的一锅两步操作方案，以中等到高的转化率（48-95％）和对映体过量（65-> 99％ee）获得了相应的手性醇）。根据ADH立体偏好，即使是在制备规模下（119-178 mg），也可以直接方法从这些有价值的手性合成子中制备两种对映体。
