• Ruthenium- and Enzyme-Catalyzed Dynamic Kinetic Asymmetric Transformation of 1,4-Diols:  Synthesis of <i>γ</i>-Hydroxy Ketones
  作者：Belén Martín-Matute、Jan-E. Bäckvall

  DOI：10.1021/jo048511h

  日期：2004.12.1

  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。

  Reaction of trialkylboranes with vinyllithium gives non-isolable lithium trialkylvinylborates which react with oxirane and methyloxirane affording 1,4- and 2,5-alkanediols, respectively. Treatment of trialkylboranes with vinylmagnesium bromide produces bromomagnesium trialkylvinylborates which analogously afford alkanediols. Successive treatment of the borates with aqueous alkali and iodine provides

  日期：2015.6.1

  highly regioselective, fluoride‐catalyzed hydrosilylation of β‐hydroxy epoxides has been developed. The reaction is modular and applicable to the synthesis of a broad range of 1,4‐diols. Fluoride is crucial for two reasons: First, it promotes the formation of a silyl ether (which contains a Si‐H bond) and, second, it enables ring opening by an intramolecular SN2 reaction through activation of the silane

  已经开发出一种新型的高度区域选择性，氟化物催化的β-羟基环氧化物的氢化硅烷化方法。该反应是模块化的，适用于多种1,4-二醇的合成。氟化物至关重要是因为两个原因：首先，它促进了甲硅烷基醚（含有Si-H键）的形成；其次，它通过分子内的S N 2反应通过硅烷的活化而使开环成为可能。该反应可以在空气中进行。
