  • Mechanism of the Palladium-Catalyzed Intramolecular Hydroalkylation of 7-Octene-2,4-dione
    作者:Hua Qian、Ross A. Widenhoefer
    DOI:10.1021/ja0293002
    日期:2003.2.1
    cis-2-acyl-3,4-dideuteriocyclohexanone (cis-3-3,4-d(2)) in 64% yield as the exclusive isotopomer. This experiment, in conjunction with additional deuterium labeling experiments, was in accord with a mechanism for the conversion of 1 to 3 catalyzed by 2 involving attack of the enol carbon atom on a palladium-complexed olefin followed by palladium migration and protonolysis from a palladium enolate complex
    PdCl(2)(CH(3)CN) 催化 (E)-7,8-dideuterio-7-octene-2,4-dione [(E)-1-7,8-d(2)] 的环化(2) (2) 以 64% 的产率形成了 cis-2-acyl-3,4-dideuteriocyclohexanone (cis-3-3,4-d(2)) 作为唯一的同位素。该实验与额外的氘标记实验相结合,符合由 2 催化的 1 到 3 转化的机制,包括烯醇碳原子对钯络合烯烃的攻击,随后钯迁移和来自钯烯醇化物的质子分解复杂的。
  • A controlled selective synthesis of dihydropyrans through tandem reaction of alkynes with diazo compounds

    日期:——
    A controlled synthesis of dihydropyrans via sequential reaction of allenoate formation and intramolecular oxo-Michael addition has been achieved.

  • Palladium-Catalyzed Carbonylative Cycloisomerization of γ-Propynyl-1,3-diketones: A Concise Route to Polysubstituted Furans
    作者:Yu Li、Zhengkun Yu
    DOI:10.1021/jo9020634
    日期:2009.11.20
    trisubstituted furan derivatives have been efficiently synthesized via palladium(II)-catalyzed intramolecular carbonylative cycloisomerization of γ-propynyl-1,3-diketones with aryl iodides and carbon monoxide. The mechanism suggests that in situ generated acylpalladium species from the carbonylation of aryl iodide initiates the reaction followed by cyclization of the enolized isomer of a 1,3-diketone substrate
    通过钯(II)催化的γ-丙炔基-1,3-二酮与芳基碘化物和一氧化碳的分子内羰基环化异构化,可以有效地合成二取代和三取代的呋喃衍生物。该机制表明,由芳基碘化物的羰基化原位生成的酰基铝物种引发了反应,然后通过碳-碳三键活化作用环化了1,3-二酮底物的烯醇化异构体。
  • Yb(OTf)3-Promoted ZnCl2-Catalyzed Conia-Ene Reaction of Linear β-Alkynic β-Dicarbonyls
    作者:Jin-Heng Li、Yu Liu、Ren-Jie Song
    DOI:10.1055/s-0030-1258213
    日期:2010.11
    An atom-economical and solvent-free ytterbium(III) triflate promoted, zinc(II) chloride catalyzed Conia-ene method has been developed for the construction of five- to six-membered-ring carbocycles. In the presence of zinc(II) chloride and ytterbium(III) triflate, a variety of linear β-alkynic β-keto esters and β-alkynic β-diketones were cyclized under neat conditions in moderate to good yields.

    已经开发了一种原子经济且无溶剂的三氟甲磺酸(III)促进的氯化锌(II)催化的Conia-ene方法,用于构建五元至六元环的碳环。在氯化锌(II)和三氟甲磺酸(III)的存在下,在纯净条件下,以中等至良好的收率将各种线性的β-链烯基β-酮酸酯和β-链烯基β-二酮环化。值得注意的是,对五或六元环碳环的选择性取决于末端炔烃上的取代基。 氯化锌(II)-三氟甲磺酸(III)-Conia-ene反应-线性β-炔烃β-二羰基-碳环
  • Copper/Silver-Cocatalyzed Conia-Ene Reaction of Linear β-Alkynic β<i>-</i>Ketoesters
    作者:Chen-Liang Deng、Ren-Jie Song、Sheng-Mei Guo、Zhi-Qiang Wang、Jin-Heng Li
    DOI:10.1021/ol7023289
    日期:2007.11.1
    A novel and general copper/silver catalytic system has been developed for the Conia-ene intramolecular reaction of linear beta-alkynic beta-ketoesters. In the presence of (CuOTf)(2)center dot C6H6 and AgSbF6 (or AgOAc), a variety of the linear 6-alkynic 6-ketoesters selectively underwent the Conia-ene intramolecular reaction in moderate to good yields.
