  • Copper-Catalyzed Oxyvinylation of Diazo Compounds
    作者:Guillaume Pisella、Alec Gagnebin、Jerome Waser
    DOI:10.1021/acs.orglett.0c01150
    日期:2020.5.15
    copper(I)-catalyzed vinylation of diazo compounds with vinylbenziodoxolone reagents (VBX) as partners is reported. The transformation tolerates diverse functionalities on both reagents delivering polyfunctionalized vinylated products. The strategy was successfully extended to a three-component/intermolecular version with alcohols. The obtained products contain synthetically versatile functional groups, such

  • Radical-Polar Crossover Reactions of Dienylboronate Complexes: Synthesis of Functionalized Allylboronic Esters
    作者:Marvin Kischkewitz、Carolin Gerleve、Armido Studer
    DOI:10.1021/acs.orglett.8b01459
    日期:2018.6.15
    Radical-polar crossover reactions of dienylboronate complexes are applied to the synthesis of functionalized secondary and tertiary allylboronic esters. The transition-metal-free three-component coupling uses readily accessible dienylboronate esters as substrates in combination with various sp3/sp2 carbon nucleophiles and commercial alkyl iodides as radical precursors. In the visible light-initiated

  • Total Synthesis of (±)-Kuwanol E
    作者:Valentina Iovine、Irene Benni、Rocchina Sabia、Ilaria D’Acquarica、Giancarlo Fabrizi、Bruno Botta、Andrea Calcaterra
    DOI:10.1021/acs.jnatprod.6b00350
    日期:2016.10.28
    The total synthesis of the Diels–Alder-type adducts (±)-kuwanol E and the heptamethyl ether derivative of (±)-kuwanon Y has been accomplished via a convergent strategy involving 2′-hydroxychalcone 6 or 9 and dehydroprenylstilbene 7, in nine steps. The synthesis features, as a key step, a Lewis acid-mediated biomimetic intermolecular Diels–Alder [4+2] cycloaddition for the construction of the cyclohexene
    的狄尔斯-阿德耳型加合物的总合成(±)-kuwanol E和七甲基醚的(±)衍生物-kuwanon Y已通过涉及2'-羟基查耳酮的会聚策略而完成的6或9和dehydroprenylstilbene 7,在九个脚步。合成的关键步骤是路易斯酸介导的仿生分子间Diels–Alder [4 + 2]环加成反应,以构建具有三个立体异构中心的环己烯骨架。值得注意的是,反应的内/外非对映选择性证明是受温度控制的。
  • Fast Synthesis of Complex Enantiopure Heterocyclic Scaffolds by a Tandem Sequence of Simple Transformations on α-Hydroxyaldehydes
    作者:Alexandre Cannillo、Stéphanie Norsikian、Pascal Retailleau、Marie-Elise Tran Huu Dau、Bogdan I. Iorga、Jean-Marie Beau
    DOI:10.1002/chem.201301712
    日期:2013.7.8
    Two tandems are faster than one! Properly sequenced reactions initiated by the Petasis aminoalcohol synthesis from boronic acids, diallylamine, and α‐hydroxyaldehydes, including free aldoses, leads to rapid construction of complex enantiopure structures (see scheme).
    两个坦丹比一个快!由Petasis氨基醇从硼酸,二烯丙基胺和α-羟醛(包括游离醛糖)合成引发的正确测序反应会导致快速构建复杂的对映纯结构(请参见方案)。
  • Synthetic studies towards the mulberry Diels–Alder adducts: H-bond accelerated cycloadditions of chalcones
    作者:Sompong Boonsri、Christian Gunawan、Elizabeth H. Krenske、Mark A. Rizzacasa
    DOI:10.1039/c2ob25115a
    日期:——
    The methyl ether derivatives 2, 4 and 6 of the mulberry Diels–Alder adducts chalcomoracin (1) and mulberrofuran C (3) and kuwanon J (5) respectively have been synthesized by a thermal [4 + 2]-cycloaddition reaction between a chalcone and dehydroprenyl diene. A H-bonded ortho OH substituent on the chalcone was found to be essential for Diels–Alder reactivity. Density functional theory calculations show that the OH group lowers the barrier for the Diels–Alder reaction by 2–3 kcal mol−1 compared with OMe. The acceleration by the OH group is traced to two transition-state effects: a stronger diene–chalcone interaction and better planarity of the aryl–diene unit.
    桑树Diels-Alder加合物白果草素(1)、桑酮C(3)和桑酮J(5)的甲基醚衍生物2、4和6分别通过查耳酮与脱氢 prenyl diene之间的热[4 + 2]环加成反应合成。研究发现,查耳酮上形成氢键的邻位羟基取代基对于Diels-Alder反应性至关重要。密度泛函理论计算表明,与甲氧基相比,羟基可将Diels-Alder反应的能垒降低2-3千卡/摩尔。羟基的加速作用归因于两种过渡态效应:更强的二烯-查耳酮相互作用和更好的芳基-二烯单元平面性。
