    用于重氮偶联级联反应的工程铱人造金属酶**
    摘要:
    人工金属酶 (ArMs) 通常用于控制催化反应的立体选择性,但控制化学选择性仍然具有挑战性。在这项研究中,我们设计了一种 dirhodium ArM 来催化重氮交叉偶联形成烯烃,该烯烃在一锅级联反应中被烯烃还原酶还原为具有高对映选择性(通常 > 99% ee)的烷烃. 级联反应所需的大量蛋白质和小分子成分对 ArM 催化的影响很小。Arm 的定向进化提高了产量和E / Z对各种底物的选择性,这转化为级联反应产率。ArM 变体的 MD 模拟用于了解辅助因子对 ArM 构象动力学的结构作用。这些结果突出了 ArMs 控制催化剂立体选择性和化学选择性的能力,以实现在复杂介质中的反应,否则会导致不希望的副反应。

    of cinnamate esters has been carried out by cathodic reduction of CC bond in an undivided cell equipped with Mg sacrificial anode and using MeCN saturated with CO2 as solvent. The yields and the ratio of mono- and dicarboxylic acids are strongly affected by various factors: cathodic material, current, charge, and temperature. The highest yield (78.9%) was obtained starting from ethyl cinnamate. Cyclic

  • Enantioselective β-Protonation by a Cooperative Catalysis Strategy
    作者:Michael H. Wang、Daniel T. Cohen、C. Benjamin Schwamb、Rama K. Mishra、Karl A. Scheidt

    日期:2015.5.13
    An enantioselective N-hetetoeyclic carbene (NHC)-catalyzed beta-protonation through the orchestration of three distinct organocatalysts has been developed. This cooperative catalyst system enhances both yield and selectivity, compared to only the NHC-catalyzed process. This new method allows for the,efficient conversion of a large scope of aryl-oxobutenoates to highly enantioenriched succinate derivatives and demonstrates the benefits of combining different activation modes in organocatalysis.
  • Highly specific fragmentation processes of isomeric mixed esters of phenylsuccinic acid under electron impact
    作者:I. Vidavsky、A. Mandelbaum、T. Tamiri、S. Zitrin
    DOI:10.1002/oms.1210260420
    日期:1991.4
    AbstractIsomeric mixed dialkyl phenylsuccinates, PhCH(COOR)CH2COOR′, undergo a highly specific elimination of ROH under electron impact. A deuterium‐labelling study showed that the hydrogen atom from the benzylic position 2 is abstracted in this process. These results suggest the occurrence of a ‘hidden’ hydrogen migration of the benzylic hydrogen atom to the carbonylic oxygen of the remote ester group, followed by the elimination of ROH from the adjacent ester group with the involvement of that hydrogen. Alkoxyl group migrations resulting in the formation of [PhCHOR]+ and [PhCHOR′]+ ions are less specific, although the migration of the remote R′O˙ is significantly preferred in all the pairs of isomers examined. Mechanisms are suggested for the formation of the two ions.

    numerous protein and small molecule components required for the cascade reaction had minimal effect on ArM catalysis. Directed evolution of the ArM led to improved yields and E/Z selectivities for a variety of substrates, which translated to cascade reaction yields. MD simulations of ArM variants were used to understand the structural role of the cofactor on ArM conformational dynamics. These results
