  • Lewis Acid Activation of Fragment-Coupling Reactions of Tertiary Carbon Radicals Promoted by Visible-Light Irradiation of EDA Complexes
    作者:Spencer P. Pitre、Tyler K. Allred、Larry E. Overman
    DOI:10.1021/acs.orglett.1c00023
    日期:2021.2.5
    The addition of tertiary carbon radicals generated from N-(acyloxy)phthalimide esters to cyclic α,β-unsaturated ketones and lactones is markedly enhanced by the addition of substoichiometric amounts of a Ln(OTf)3. The reaction is accomplished by irradiation with visible light in the absence of a photosensitizer and is suggested to proceed by excitation of a ternary electron donor–acceptor complex between
    通过添加亚化学计量的Ln(OTf)3,可以显着增强将N-(酰氧基)邻苯二甲酰亚胺酯生成的叔碳基团加到环状α,β-不饱和酮和内酯上。该反应通过在不存在光敏剂的情况下用可见光照射完成,并建议通过在NHPI酯,Hantzsch酯和Ln(OTf)3之间激发三元电子供体-受体配合物来进行。
  • Total Synthesis of Neoaltenuene
    作者:Martina Altemöller、Joachim Podlech
    DOI:10.1002/ejoc.200900125
    日期:2009.5
    The total synthesis of neoaltenuene, a toxin produced by alternaria fungi, has been achieved for the first time in 14 steps in a yield of 10 % starting from quinic acid and phloroglucinic acid, the longest linear sequence consisting of 10 steps. The key reaction was a palladium-catalyzed Suzuki-type coupling of an arene boronate with an iodinated cyclohexene.4a-epi-Neoaltenuene, a non-natural isomer
    由链格孢属真菌产生的毒素新烯烃的全合成首次以奎尼酸和间苯三甲酸为起始原料,分 14 步完成,产率为 10%,最长的线性序列由 10 步组成。关键反应是钯催化的芳烃硼酸酯与碘化环己烯的 Suzuki 型偶联。4a-epi-Neoaltenuene,一种非天然异构体也已类似地合成。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
  • The effect of diethylamine on Stille alkylations with tetraalkylstannanes
    作者:M. Teresa Barros、Christopher D. Maycock、Mariana I. Madureira、M. Rita Ventura
    DOI:10.1039/b103072h
    日期:——
    The addition of diethylamine to Stille alkylation reactions using stannanes improves yields by reducing β-hydride elimination and reduction reactions, it also serves as a substitute for other additives such as Cu(I)I.
    二乙胺的添加用于斯蒂尔烷基化反应中,可以通过降低β-氢消除和还原反应来提高产率,同时它也可以作为其他助剂(如Cu(I)I)的替代品。
  • Synthesis of the B-<i>seco</i> limonoid core scaffold
    作者:Hanna Bruss、Hannah Schuster、Rémi Martinez、Markus Kaiser、Andrey P Antonchick、Herbert Waldmann
    DOI:10.3762/bjoc.10.15
    日期:——
    towards the structurally complex and highly decorated framework of B-seco limonoid natural products by means of a [3,3]-sigmatropic rearrangement are described. Detailed model studies reveal, that an Ireland-Claisen rearrangement can be employed to construct the central C9-C10 bond thereby giving access to the B-seco limonoid scaffold. However, application of the developed strategy ended up failing
    描述了通过 [3,3]-sigmatropic 重排对 B-seco 柠檬苦素类天然产物的结构复杂和高度装饰框架的合成研究。详细的模型研究表明,可以采用爱尔兰-克莱森重排来构建中央 C9-C10 键,从而获得 B-seco 柠檬苦素支架。然而,开发策略的应用最终在更复杂和空间要求更高的系统中失败。
  • Asymmetric Total Synthesis of Cephanolide A
    作者:Hongyuan Zhang、Haibing He、Shuanhu Gao
    DOI:10.1002/anie.202009562
    日期:2020.11.9
    The first asymmetric total synthesis of cephanolide A, a complex hexacyclic C18 dinorditerpenoid from cephalotaxus sinensis, was achieved. The synthesis features a convergent strategy, which provides a flexible approach to prepare the biogenetically cephalotaxus diterpenoids and structurally related derivatives for biological studies. A mild intramolecular Prins cyclization was developed to construct
    头孢洛奈德A(一种复杂的六环C 18)的首次不对称全合成获得了来自中国头孢的双去二萜。该合成具有收敛策略,该策略提供了灵活的方法来制备生物遗传性头孢类双萜和与结构相关的衍生物,以进行生物学研究。开发了温和的分子内Prins环化反应以构建中央六氢芴醇骨架(A-B-C环),该骨架依赖于最初提出的加氢酰化策略。应用远程羟基定向氢化以立体定向还原四取代的烯酮单元。有效地利用一系列环形成步骤,包括内酯化,阳离子介导的醚化和Friedel-Crafts环化,来锻造笼状骨架。
