Enzymatic kinetic resolution of unsymmetrical 1,4-diols in combination with a ruthenium-catalyzed hydrogen transfer process led to a dynamic kinetic asymmetric transformation (DYKAT) of the least hindered alcohol. Oxidation of the second hydroxy group takes place under the reaction conditions leading to the formation of γ-acetoxy ketones in high enantiomeric purity.
不对称的1,4-二醇的酶动力学拆分与钌催化的氢转移过程相结合,导致了受阻最少的醇的动态动力学不对称转化(DYKAT)。第二羟基的氧化在反应条件下进行,导致形成高对映体纯度的γ-乙酰氧基酮。
