    Six- and five-membered 3-alkoxy-2-lithiocycloalkenes: new stable non-anionic β-functionalised organolithium compounds
    摘要:
    Naphthalene-catalysed reductive lithiation of various functionalised chlorocycloalkenes 18 leads to the corresponding non-anionic beta-alkoxyfunctionalised organolithium reagents 14. Their reaction with different electrophiles, such as water, aldehydes, ketones and imines, gave the expected products 19 and 24. The diastereoselection in the reaction with aldehydes can be modified by the use of different additives. In the case of using 3-methoxy-2-chlorocyclopentene (18a) as starting material, and depending on reaction time, unexpected bicyclopentadiene derivatives 25 were isolated, together with the expected compounds 24.

  • Multimetallic Ni- and Pd-Catalyzed Cross-Electrophile Coupling To Form Highly Substituted 1,3-Dienes
    作者:Astrid M. Olivares、Daniel J. Weix
    DOI:10.1021/jacs.7b13601
    日期:2018.2.21
    synthesis of highly substituted 1,3-dienes from the coupling of vinyl bromides with vinyl triflates is reported for the first time. The coupling is catalyzed by a combination of (5,5'-bis(trifluoromethyl)-2,2'-bipyridine)NiBr2 and (1,3-bis(diphenylphosphino)propane)PdCl2 in the presence of a zinc reductant. This method affords tetra- and penta-substituted 1,3-dienes that would otherwise be difficult
    首次报道了由溴乙烯与三氟甲磺酸乙烯酯偶联合成高度取代的1,3-二烯。该偶联反应由 (5,5'-双(三氟甲基)-2,2'-联吡啶)NiBr2 和 (1,3-双(二苯基膦)丙烷)PdCl2 在锌还原剂存在下的组合催化。该方法提供了四取代和五取代的1,3-二烯,否则这些1,3-二烯很难获得,并且可以耐受富电子和贫电子取代基、杂环、芳基溴和频哪醇硼酸酯。从机理上讲,该反应似乎是通过镍和钯中心之间异常的锌介导的乙烯基转移来进行的。
  • Synthesis of Halomethyl Isoxazoles/Cyclic Nitrones via Cascade Sequence: 1,2-Halogen Radical Shift as a Key Link

    日期:2018.5.18
    A novel iminoxyl radical-promoted dichotomous regioselective 5-exo-trig cyclization onto vinylic halogen/1,2-halogen radical shift sequence is developed for the synthesis of halomethyl isoxazoles/cyclic nitrones using β-halo-β,γ- and γ-halo-γ,δ-unsaturated ketoximes as the substrates and PhI(OAc)2/TEMPO as the oxidation system. DFT calculations reveal that a halogen-bridged three-membered ring transition
    开发了一种新的亚氨基自由基促进的二分体区域选择性5-exo-trig环化到乙烯基卤素/ 1,2-卤素自由基转移序列上,用于使用β-卤代-β,γ-和γ-卤代合成卤代甲基异恶唑/环硝酮-γ,δ-不饱和酮肟为底物,PhI(OAc)2 / TEMPO为氧化体系。DFT计算表明,卤代桥三元环跃迁态与1,2-Cl- / Br原子移位有关,而1,2-I原子迁移可通过消除/再分配机制加以考虑。指示迁移能力按以下顺序排列:I> Br> Cl。

    DOI:10.1016/j.tetlet.2009.08.038
    日期:2009.11
    A procedure for the α-chlorination or bromination of a number of α,β-unsaturated carbonyls, and the dichlorination or bromination of alkenes, is developed using bisacetoxyiodobenzene (BAIB) and the HCl or HBr salt of pyridine. The reaction proceeds in an acceptable to a good yield and has a broad substrate scope. The dibromination is also achieved using a chiral I[V] reagent, although little enantioselectivity
    使用双乙酰氧基碘苯(BAIB)和吡啶的HCl或HBr盐开发了多种α,β-不饱和羰基的α-氯化或溴化方法,以及烯烃的二氯化或溴化方法。反应以可接受的产率进行,并具有良好的收率,并且具有广泛的底物范围。尽管可以实现很少的对映选择性,但是也可以使用手性I [V]试剂实现二溴化。
  • Halogenation of Carbonyl Compounds by an Ionic Liquid, [AcMIm]X, and Ceric Ammonium Nitrate (CAN)
    作者:Brindaban C. Ranu、Laksmikanta Adak、Subhash Banerjee
    DOI:10.1071/ch07061
    日期:——
    An ionic liquid, acetylmethylimidazolium halide ([AcMIm]X), in combination with ceric ammonium nitrate promotes halogenations of a wide variety of ketones and 1,3-keto esters at the α-position. The ionic liquid acts here as reagent as well as reaction medium, and thus the reaction does not require any organic solvent or conventional halogenating agent. The reaction is completely arrested when the radical
    离子液体乙酰甲基咪唑鎓卤化物 ([AcMIm]X) 与硝酸铈铵结合可促进多种酮和 1,3-酮酯在 α 位的卤化。离子液体在此既充当试剂又充当反应介质,因此该反应不需要任何有机溶剂或常规卤化剂。当使用自由基猝灭剂 TEMPO 时,反应完全停止。还提出了一种似是而非的激进机制。

    日期:2013.12
    The use of water as a nucleophile for Michael additions is still a challenge in organic chemistry. In this report we describe the use of amino acids as catalysts for the Michael addition of water to ?,?-unsaturated ketones. All 20 proteinogenic amino acids were screened and L-lysine was identified as the best candidate. To obtain a better insight and to determine the minimum requirements of the catalyst
