  • 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,铁催化了溴乙缩醛的5- Exo- trig自由基还原环化反应。发现铁(II)和铁(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,铁(III)可以还原为铁(II)预催化剂,在该反应机理中,阴离子氢化铁(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(碘衍生物与溴衍生物)和预催化混合物均对确定反应结果具有决定性作用。
  • Copper-Catalyzed Dicarbofunctionalization of Unactivated Olefins by Tandem Cyclization/Cross-Coupling
    作者:Surendra Thapa、Prakash Basnet、Ramesh Giri

    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,用两个碳基实体对 1,2 位的未活化烯烃进行双官能化。该方法利用衍生自烯烃系烷基/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,其被芳基和杂芳基碘化物拦截。使用这种新方法可以合成各种(芳甲基)碳环和杂环(N,O)。
  • Iron-Catalyzed Reductive Radical Cyclization of Organic Halides in the Presence of NaBH4: Evidence of an Active Hydrido Iron(I) Catalyst
    作者:Audrey Ekomié、Guillaume Lefèvre、Louis Fensterbank、Emmanuel Lacôte、Max Malacria、Cyril Ollivier、Anny Jutand

    complexes such as FeCl2 and [FeCl2(dppe)2] (dppe=1,2‐bisdiphenylphosphinoethane) are efficient precatalysts for the radical cyclization of unsaturated iodides and bromides in the presence of NaBH4 (see scheme). Cyclic voltammetry studies suggests that the reaction occurs through a radical mechanism via an anionic hydrido iron(I) species as the key intermediate for the activation of the substrates by electron
    铁制造的东西:铁(II)络合物,例如FeCl 2和[FeCl 2(dppe)2 ](dppe = 1,2-双二苯基膦基乙烷)是在NaBH 4存在下对不饱和碘化物和溴化物进行自由基环化的有效预催化剂(请参阅方案)。循环伏安法研究表明,该反应是通过自由基机理发生的,该阴离子机理是阴离子氢化铁(I)作为电子转移活化底物的关键中间体。

    undergo group transfer cyclization to afford 2-substituted 4-[(aryltelluro)methyl]tetrahydrofurans (cis/trans = 1/3-1/10). The aryl beta-(prop-2-ynyloxy)alkyl tellurides similarly afforded 2-substituted 4-[(aryltelluro)methylene]tetrahydrofurans with an E/Z-ratio close to unity. The beta-(allyloxy)alkyl aryl selenides and aryl beta-(prop-2-ynyloxy)alkyl selenides failed to undergo group transfer cyclization
    单取代的环氧化物从空间上受阻最小的一面通过苯碲酸根和苯硒酸根试剂进行区域特异性开环,分别得到芳基β-羟烷基碲化物和硒化物。通过在四氢呋喃中用烯丙基溴/氢化钠处理将这些材料进行O-烯丙基化,并在与炔丙基溴/氢化钠反应时将O-prop-2-炔化。在含有40 mol%的六丁基二锡的苯中进行光解后,发现β-(烯丙氧基)烷基芳基碲化物经历了基团转移环化,从而获得了2-取代的4-[((芳基碲基)甲基]四氢呋喃(顺式/反式= 1 / 3- 1/10)。芳基β-(丙-2-炔氧基)烷基碲化物类似地得到E / Z比接近于1的2-取代的4-[(芳基碲基)亚甲基]四氢呋喃。β-(烯丙氧基)烷基芳基硒化物和芳基β-(丙-2-基氧基氧基)烷基硒化物未进行基团转移环化。在氢化三丁基锡和2,2'-偶氮二异丁腈的存在下,发现前一种化合物以高收率进行还原性自由基环化,得到2-取代的4-甲基四氢呋喃(顺式/反式= 1 / 3-1

    organic halides in the presence of NaBH4. Mechanistic investigations have established that the ligand bound to the metal center (acetonitrile versus ethylenebis(diphenylphosphine) (dppe)) plays a crucial role in the structure and reactivity of the active anionic iron(I) hydride ([HFeCl(dppe)2]−) and borohydride ([(η1-H3BH)FeCl(NCCH3)4]−) with unsaturated haloacetals. This work provides new insights
