2-Telraloncs mono- and disubstitutcd with methoxy or hydroxy groups in the aromatic ring are hydrogenated to 2-tetralols in good yields by non-fermenting baker's yeast. The prevalent enantioform of the reduction product and its e.e. were found to depend on the substitution pattern. In one case, i.e. the biotransformation of 5-mcthoxy-2-tetralone into the corresponding 2-tetralol, an e.e. ≥ 98% was
通过不发酵面包酵母以高收率将具有芳香环中的甲氧基或羟基的单-和2-取代的2-Telraloncs氢化成2-四醇。发现还原产物及其ee的普遍对映体取决于取代模式。在一种情况下,即5-甲氧基-2-四氢萘酮生物转化为相应的2-四氢萘酚,观察到ee≥98%。提出了一个简单的抽象模型,用于解释和预测2-四氢萘酮在酵母介导的羰基还原反应中的立体化学结果。
