  • Radical based annulations of iodo lactams
    作者:Spencer Knapp、Frank S Gibson、Yun H Choe
    DOI:10.1016/s0040-4039(00)97856-0
    日期:1990.1
    N-Alkylation of iodo lactams with reactive alkyl halides, or of the derived selenide lactams with less reactive alkyl halides, leads to substrates for free radical initiated cyclization to pyrrolizidinones and indolizidinones, e. g. 2 → 3. The first examples of iodide / vinyl bromide, selenide / aldehyde, and selenide / vinyl chloride radical cyclizations are described.
    碘代内酰胺与反应性烷基卤化物的N-烷基化,或衍生的硒代内酰胺与反应性较低烷基卤化物的N-烷基化,导致底物被自由基引发环化为吡咯烷二酮和吲哚并二酮,例如2 → 3。描述了碘化物/溴乙烯,硒化物/醛和硒化物/氯乙烯自由基环化的第一个实例。
  • A Unified and Desymmetric Approach to Chiral Tertiary Alkyl Halides
    作者:Yin Zheng、Suihan Zhang、Kam-Hung Low、Weiwei Zi、Zhongxing Huang

    日期:2022.2.2
    can reductively desymmetrize a large collection of easily available halomalonic esters to α-halo-β-hydroxyesters. These polyfunctionalized tertiary alkyl fluorides, chlorides, and bromides proved to be useful intermediates toward fluorinated drug analogs and polyhalogenated monoterpenes. The facile intramolecular epoxidation of the chiral chloride and bromide products has also enabled expeditious access
    对映体富集的叔烷基卤化物普遍存在于生物活性分子中,可作为通用合成中间体来构建复杂结构。虽然常规获得这些基序通常取决于立体选择性碳-卤素或碳-碳键形成反应,但相比之下,使用卤代和前手性四取代碳的不对称方法在很大程度上难以捉摸。在这里,我们报告了一套具有脯氨醇或哌啶醇衍生的四齿配体的双核锌催化剂可以将大量容易获得的卤代丙二酸酯还原为α-卤代-β-羟基酯。这些多官能化的叔烷基氟化物、氯化物和溴化物被证明是氟化药物类似物和多卤化单萜的有用中间体。
  • Total Synthesis of Indole Alkaloid Alsmaphorazine D
    作者:Chenlong Zhu、Zhaobo Liu、Guanyu Chen、Kai Zhang、Hanfeng Ding
    DOI:10.1002/anie.201409827
    日期:2015.1.12
    A concise total synthesis of rac‐alsmaphorazine D has been described for the first time. The efficient synthetic strategy features four key transformations: 1) a catalytic intramolecular oxidative cyclization for the δ‐lactamindole backbone; 2) an oxidative cyclic aminal formation for the hexahydropyrrolo[2,3‐b]pyrrole framework; 3) a transannular radical cyclization for the construction of the diazabicyclo[3

  • Hydrogen‐Atom‐Transfer‐Initiated Radical/Polar Crossover Annulation Cascade for Expedient Access to Complex Tetralins
    作者:Lucas Johnson、Griffin Barnes、Sebastian Fernandez、Christopher D. Vanderwal
    DOI:10.1002/anie.202303228
    日期:——
    A radical/polar crossover manifold permits annulations between allylarenes and Giese-type accepters, providing a route to functionalized tetralins. The reaction conditions are mild and therefore exhibit significant functional group tolerance. The annulation products are formally cycloadducts of styrenes and electron-deficient alkenes, and they can be used to form a variety of strained ring products
    自由基/极性交叉流形允许烯丙芳烃和吉斯型受体之间形成环,从而提供了官能化四氢化萘的途径。反应条件温和,因此表现出显着的官能团耐受性。环化产物形式上是苯乙烯和缺电子烯烃的环加合物,它们可用于形成各种应变环产物。
  • Radical routes to indolizidines. Synthesis of (-)-slaframine
    作者:Spencer Knapp、Frank S. Gibson
    DOI:10.1021/jo00044a011
    日期:1992.8
    The synthesis of (-)-slaframine (5) was executed in 11 steps and 25% overall yield from resolved 3(S)-hydroxy-4-pentenamide (22). Two cyclization reactions were used to form the indolizidine skeleton and also to provide the necessary stereocontrol at C-8a and C-6 of the natural product. "Iodolactamization" of 22 gave selectively the cis-pyrrolidinone 21. Later in the synthesis, a silane-mediated radical cyclization of the phenylseleno lactam 33 gave selectively the 6-alpha-hydroxyindolizidinone 35a, an event predictable from model studies-such as 14c --> 15c. Replacement of hydroxy with azido and reduction of the lactam carbonyl gave "slaframine azide", 38, a stable and easily convertible immediate precursor to 5.
