The formation of cis-2-alkylcyclohexanol products from horse liver alcohol dehydrogenase-catalyzed reductions of 2-alkylcyclohexanones has been detected for the first time. The cis-alcohols are minor (<4%) products, with the isomeric trans-products being heavily predominant under all conditions. cis-Alcohol production can be suppressed by suitable manipulation of the reaction conditions.

首次检测到由马肝醇脱氢酶催化还原 2-烷基环己酮生成顺式-2-烷基环己醇产物。顺式醇是次要的 (<4%) 产物,异构反式产物在所有条件下都占主导地位。顺式醇的产生可以通过适当操作反应条件来抑制。通过在适当的缓冲液(如 Tris-HCl)中在最低 [E]/[S] 和可能的 pH 条件下操作,并通过最大限度地减少反应时间,有利于反式醇的完全形成。结果与先前用类似的 3-烷基四氢噻喃-4-one 底物观察到的顺式醇形成相似。
