    摘要:
    我们报告了一种新的铁催化 I/Zn 交换,允许将伯或定制的仲烷基碘化物转化为相应的烷基碘化锌。在位置 5 存在远程双键的情况下,观察到非对映选择性闭环。这些锌试剂在转金属化为铜物质(使用 CuCN ⋅ 2LiCl)后或在 Pd 催化下,使用典型的亲电试剂(烯丙基溴化物、酰氯或芳基碘化物)进行淬灭,得到各种多功能产物。

  • Iron(II) catalyzed reductive radical cyclization reactions of bromoacetals in the presence of NaBH4: optimization studies and mechanistic insights
    作者:Sara H. Kyne、Christophe Lévêque、Shiwen Zheng、Louis Fensterbank、Anny Jutand、Cyril Ollivier

    5-Exo-trig radical reductive cyclization reactions of bromoacetals are catalyzed by iron in the presence of the reducing agent NaBH4. Both iron(II) and iron(III) were found to effectively mediate these reactions. As shown by cyclic voltammetry, iron(III) can be reduced to an iron(II) precatalyst before passing through an identical reaction mechanism in which monoelectronic activation of the substrate
    在还原剂NaBH 4的存在下,催化了乙缩醛的5- Exo- trig自由基还原环化反应。发现(II)和(III)均可有效介导这些反应。如循环伏安法所示,在通过相同的反应机理之前,(III)可以还原为(II)预催化剂,在该反应机理中,阴离子(I)络合物会发生底物的单电子活化。进一步的研究已经确定,底物(生物生物)和预催化混合物均对确定反应结果具有决定性作用。

    electron-transfer strategy using low-valent iron pentacarbonyl [Fe(CO)5] to generate radical species from alkyl iodides was achieved. A range of pyrrolidines, tetrahydrofurans, and carbocycles were synthesized via 5-exo cyclization reactions of alkyl radical intermediates generated by electron transfer from a system involving Fe(CO)5, 1,10-phenanthroline, and diisopropylamine. Moreover, tandem addition
    实现了使用低价五羰基铁[Fe(CO)5 ]从烷基生成自由基物种的电子转移策略。吡咯烷,四氢呋喃,和环的范围被通过5-合成外型通过从涉及的Fe(CO)的系统的电子转移产生烷基中间体的环化反应5,1,10-咯啉,和二异丙胺。此外,还探讨了与迈克尔受体的串联加成反应。光物理和电化学研究支持一种涉及电子从低价还原剂转移至烷基的机理。
  • A Free‐Radical Reduction and Cyclization of Alkyl Halides Mediated by FeCl <sub>2</sub>

    日期:2019.5.20
    Iron mediated catalytic reactions are of great interest in the field of organic synthesis because they are economic and naturally abundant. However, the use of iron catalyst in the field of free radical cyclization or reduction of alkyl halides remains limited. Here we describe the use of an unprecedented combination of iron and zinc in the reduction and 5‐exo‐trig radical cyclization of alkyl halides
    介导的催化反应在有机合成领域中非常受关注,因为它们既经济又天然。然而,在自由基环化或烷基卤化物的还原领域中催化剂的使用仍然受到限制。在这里,我们描述了在没有添加配体添加剂的条件下,在温和条件下使用前所未有的结合物对卤代烷进行还原和5 -exo-trig自由基环化的方法。该方法的特点是范围广,官能团耐受性强,并且使用1,4-环己二烯作为源,有助于纯化。
  • Indium hydride: a novel radical initiator in the reduction of organic halides with tributyltin hydride
    作者:Katsuyuki Inoue、Akemi Sawada、Ikuya Shibata、Akio Baba
    DOI:10.1016/s0040-4039(01)00816-4
    日期:2001.7
    Dichloroindium hydride (Cl2InH), which was generated in situ by transmetallation between tributyltin hydride and indium trichloride, acted as a novel radical initiator for the reduction of organic halides with tributyltin hydride. The reaction was revealed to proceed through a radical process under non-oxygen conditions at room temperature, and to be applicable to intramolecular radical cyclizations
    通过化三丁基锡三氯化铟之间的属转移反应原位生成的化二(Cl 2 InH)充当了新型的自由基引发剂,用于用化三丁基锡还原有机卤化物。揭示了该反应在室温下在无条件下通过自由基过程进行,并且适用于分子内自由基环化。
  • Copper-Catalyzed Dicarbofunctionalization of Unactivated Olefins by Tandem Cyclization/Cross-Coupling
    作者:Surendra Thapa、Prakash Basnet、Ramesh Giri
    DOI:10.1021/jacs.7b01922
    日期:2017.4.26
    We present a strategy that difunctionalizes unactivated olefins in 1,2-positions with two carbon-based entities. This method utilizes alkyl/arylzinc reagents derived from olefin-tethered alkyl/aryl halides that undergo radical cyclization to generate C(sp3)-Cu complexes in situ, which are intercepted with aryl and heteroaryl iodides. A variety of (arylmethyl)carbo- and heterocycles (N, O) can be synthesized
    我们提出了一种策略,用两个基实体对 1,2 位的未活化烃进行双官能化。该方法利用衍生自烃系烷基/芳基卤化物的烷基/芳基锌试剂,这些烷基/芳基卤化物经过自由基环化以原位生成 C(sp3)-Cu 配合物,其被芳基和杂芳基化物拦截。使用这种新方法可以合成各种(芳甲基环和杂环(N,O)。
