  摘要：

  在Ir–ReO x / SiO 2催化剂上将四氢糠醇加氢水解为1,5-戊二醇和其他相关的底物，例如3-羟基四氢呋喃和1,2-环己二醇。TOF值高于Rh-ReO x / SiO 2，据报道它是一种有效的催化剂。对产物的选择性（与底物中C-OH基团相邻的C-O键解离了）与Rh-ReO x / SiO 2相当或更高。除1,2-环己二醇外，大多数底​​物的氢解反应都是通过直接机理进行的，其中氢分子形成的氢化物会攻击C–O键的反位置。在氢解1，2-环己二醇的情况下，不利于C–O键反位的攻击，涉及脱氢成2-羟基环己酮的间接机理是导致环己醇形成的原因。

• Chemo- and Regioselective Synthesis of Acyl-Cyclohexenes by a Tandem Acceptorless Dehydrogenation-[1,5]-Hydride Shift Cascade
  作者：Lewis B. Smith、Roly J. Armstrong、Daniel Matheau-Raven、Timothy J. Donohoe

  acceptorless dehydrogenation of the diol followed by a redox-neutral cascade process, which is independent of the iridium catalyst. Deuterium labeling studies established that the key step of this cascade involves a novel base-mediated [1,5]-hydride shift. The cyclohexenyl ketone products could readily be cleaved under mildly acidic conditions to access a range of valuable substituted cyclohexene derivatives

  描述了一种从五甲基苯乙酮和 1,5-二醇中获得取代的酰基环己烯的原子经济方法。该过程由铱 (I) 催化剂与庞大的富电子膦配体 (CataCXium A) 共同催化，该配体有利于无受体脱氢反应，而不是共轭还原成相应的环己烷。该反应产生水和氢气作为唯一的副产物，并且可以使用该方法以非常高的产率合成范围广泛的官能化酰基环己烯产物。进行了一系列对照实验，结果表明该过程是由二醇的无受体脱氢引发的，然后是氧化还原中性级联过程，该过程与铱催化剂无关。氘标记研究表明，该级联的关键步骤涉及一种新型碱介导的 [1,5]-氢化物转移。环己烯基酮产物在弱酸性条件下很容易裂解，以获得一系列有价值的取代环己烯衍生物。

  日期：2019.9.2

  Hydrogen borrowing catalysis serves as a powerful alternative to enolate alkylation, enabling the direct coupling of ketones with unactivated alcohols. However, to date, methods that enable control over the absolute stereochemical outcome of such a process have remained elusive. Here we report a catalytic asymmetric method for the synthesis of enantioenriched cyclohexanes from 1,5‐diols via hydrogen

  氢借位催化是烯醇化烷基化的有力替代方法，可将酮与未活化的醇直接偶联。然而，迄今为止，仍无法控制这种方法的绝对立体化学结果的方法。在这里，我们报告了一种通过氢借位催化从1,5-二醇合成对映体富集的环己烷的催化不对称方法。该反应是通过添加手性铱（I）络合物来介导的，该络合物能够在该过程中赋予高水平的对映选择性。已经制备了一系列对映体富集的环己烷，并且通过结合实验和DFT研究探索了对映体诱导的模式。
