  • <scp>Palladium‐Catalzyed</scp> Atroposelective <scp>16‐Membered</scp> Macrocyclization: Total Synthesis of Isoplagiochin D <sup>†</sup>
    作者:Junwei Xi、Zhenhua Gu

    日期:2020.10
    axial chirality in one biaryl structure, and semistable axial chirality in the other biaryl moiety. We reported here an unprecedented example for the catalytically asymmetric synthesis of ring‐strained atropisomers via Pdcatalyzed macrocyclization between benzyl halides and carbenes. This newly developed Pdcatalyzed asymmetric macrocyclization protocol enabled us a quick synthesis of isoplagiochin D
    Isoplagiochin D是一个环应变大环双联苄基,在一个联芳基结构中显示稳定的轴向手性,在另一个联芳基部分中显示半稳定的轴向手性。我们在这里报道了一个前所未有的例子,该实验通过苄基卤化物和卡宾化合物之间的钯催化大环化反应,催化不对称合成环应变阻转异构体。这种新开发的Pd催化的不对称大环化方案使我们能够以高对映选择性的方式快速合成异硫菌素D。
  • Towards the enantioselective synthesis of axially chiral cyclic bis(bibenzyls) through sulfoxide-controlled diastereoselective Suzuki coupling

    Natural macrocyclic bis(bibenzyls) exhibiting configurationally stable axially chiral biaryls are of high interest from a structural as well as from a synthetic point of view. An enantiopure sulfinyl auxiliary controlling an atropo-diastereoselective biaryl Suzuki coupling reaction has been investigated and promising results for the preparation of the biaryl moiety of cyclic bis(bibenzyls) like isoplagiochins
    从结构以及从合成的观点来看,表现出构型稳定的轴向手性联芳基的天然大环双(联苄基)备受关注。已经研究了控制对映体-非对映选择性联芳基Suzuki偶联反应的对映体纯亚磺酰基助剂,并获得了制备环状双(联苄基)如异斜烷C或D的联芳基部分的有希望的结果。此外,讨论了解释过渡态期间的立体选择性和包括双重立体分化的替代效应的模型。
  • Access to the Enantiopure Axially Chiral Cyclophane Isoplagiochin D through Atropo-diastereoselective Heck Coupling
    作者:Daniel Meidlinger、Lisa Marx、Catalina Bordeianu、Sabine Choppin、Françoise Colobert、Andreas Speicher

    日期:2018.7.16
    Considering cyclophanes with axially chiral biaryl moieties, the control of atroposelectivity is essential with biological activity and is synthetically challenging. We report an atroposelective approach involving Heck cyclization, which for the first time enables the total synthesis of an enantiopure macrocyclic bis(bibenzyl), namely isoplagiochin D. An enantiopure sulfinyl auxiliary in the ortho position
    大环化通常是合成环烷型天然产物的关键步骤。考虑到具有轴向手性联芳基部分的环烷,对于生物活性来说,对熵选择性的控制是必不可少的,并且在合成上具有挑战性。我们报告涉及的Heck环合,即在第一次使一个对映体纯的大环双(联苄)的总合成一个atroposelective的方法,即isoplagiochin D.一种对映体纯的亚磺酰在辅助邻联芳基轴(静止柔性)的位置来引起对非对映体选择性的Heck偶联(高达98%de)。亚磺酰基助剂的无痕特征使得能够引入羟基,从而也使目标分子具有98%ee。
  • Syntheses of macrocyclic bisbibenzyls on solid support
    作者:Andreas Speicher、Timo Backes、Stefan Grosse
    DOI:10.1016/j.tet.2005.09.048
    日期:2005.12
    We describe a route for the polymer supported total synthesis of the cyclic bisbibenzyls of the isoplagiochin type found in liverworts. TentaGel (R) resins were used as solid support for a sequence involving Suzuki, Wittig and hydrogenation protocols. The polymer linked intermediates could be characterized by HR-MAS NMR. This route is to be extended to the synthesis of small libraries of differently halogenated derivatives. (c) 2005 Elsevier Ltd. All rights reserved.
