  • 1,3‐Diketone‐Modified Nucleotides and DNA for Cross‐Linking with Arginine‐Containing Peptides and Proteins
    作者:Denise‐Liu' Leone、Martin Hubálek、Radek Pohl、Veronika Sýkorová、Michal Hocek
    DOI:10.1002/anie.202105126
    日期:2021.8.2
    thymidine 5′-O-mono- and triphosphate were synthesized through CuAAC click reaction of diketone-alkynes with 5-azidomethyl-dUMP or -dUTP. The triphosphates were good substrates for KOD XL DNA polymerase in primer extension synthesis of modified DNA. The nucleotide bearing linear 3,5-dioxohexyl group (HDO) efficiently reacted with arginine-containing peptides to form stable pyrimidine-linked conjugates, whereas
    通过二酮-炔烃与 5-叠氮甲基-dUMP 或 -dUTP 的 CuAAC 点击反应合成线性或支链 1,3-二酮连接的胸苷 5'- O-单磷酸三磷酸。在修饰 DNA 的引物延伸合成中,三磷酸盐是 KOD XL DNA 聚合酶的良好底物。带有线性 3,5-二氧代己基 (HDO) 的核苷酸可与含精酸的肽有效反应,形成稳定的嘧啶连接缀合物,而支链 2-乙酰基-3-氧代-丁基 (PDO) 基团则不具有反应性。与赖酸或末端基反应形成易于解的烯胺加合物。DNA 中的这种反应性 HDO 修饰用于与含 Arg 的肽或蛋白质(例如组蛋白)进行生物缀合和交联。
  • A controlled selective synthesis of dihydropyrans through tandem reaction of alkynes with diazo compounds

  • 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(II)催化的γ-丙炔基-1,3-二酮与芳基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生物。该机制表明,由芳基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.
