    Oxidative Cross-Coupling of β,β-Difluoroenol Silyl Ethers with Nucleophiles:  A Dipole-Inversion Method to Difluoroketones
    摘要:
    Oxidative cross-coupling of alpha-aryl-beta,beta-difluoroenol silyl ethers with heteroaromatics in the presence of Cu(OTf)(2) in wet acetonitrile proceeds smoothly, affording heteroaryldifluoromethyl aryl ketones in 61-88% yields. Alcohols also react as nucleophiles under the same conditions to provide alkoxydifluoromethyl aryl ketones in 73-80% yields.

    光氧化还原催化未活化 C(sp3)–H 键的 N 定向区域选择性二氟烷基化
    摘要:
    我们报道了酰胺中未活化的 C(sp 3 )–H 键的氧化还原中性、可见光介导的二氟烷基化,通过以氮为中心的自由基触发分子内氢原子转移。值得注意的是,所有类型(叔键、仲键和伯键)的 γ-C(sp 3 )–H 键均表现出优异的反应性。该方法为将 α,α-二氟酮片段区域选择性引入有机分子提供了一种简便的途径。此外,所得的宝石二氟酮可以很容易地转化为结构多样的含二氟分子,在药物化学和化学生物学中提供了广泛的潜在应用。

  • Base-catalysed <sup>18</sup>F-labelling of trifluoromethyl ketones. Application to the synthesis of <sup>18</sup>F-labelled neutrophil elastase inhibitors
    作者:Denise N. Meyer、Miguel A. Cortés González、Xingguo Jiang、Linus Johansson-Holm、Monireh Pourghasemi Lati、Mathias Elgland、Patrik Nordeman、Gunnar Antoni、Kálmán J. Szabó

    A new method for the fluorine-18 labelling of trifluoromethyl ketones has been developed. This method is based on the conversion of a–COCF3 functional group to a difluoro enol silyl ether followed by halogenation and fluorine-18 labelling. The utility of this new method was demonstrated by the synthesis of fluorine-18 labelled neutrophil elastase inhibitors, which are potentially useful for detection
    开发了一种用于三氟甲基酮的氟 18 标记的新方法。该方法基于将 a-COCF 3官能团转化为二氟烯醇甲硅烷基醚,然后进行卤化和氟 18 标记。氟 18 标记的中性粒细胞弹性蛋白酶抑制剂的合成证明了这种新方法的实用性,这些抑制剂可能用于检测炎症性疾病。
  • p-Toluenesulfonic Acid-Catalyzed Reaction of Phthalaldehydic Acids with Difluoroenoxysilanes: Access to 3-Difluoroalkyl Phthalides

    A convenient approach for the synthesis of 3-difluoroalkyl phthalides has been developed from phthalaldehydic acids and difluoroenoxysilanes by using relatively inexpensive p-toluenesulfonic acid monohydrate (PTSA) as a catalyst. A series of 3-difluoroalkyl phthalides and cyclic difluoroalkyl ethers were obtained in up to 99% yield. The products obtained could be readily converted into difluoroalkyl

    We report a highly stereoselective synthesis of all‐carbon or fluorinated tetrasubstituted alkenes from diazo reagents and fluorinated enol silyl ethers, using C−F bond as a synthetic handle. Cationic AuI catalysis plays a key role in this reaction. Remarkable fluorine effects on the reactivity and selectivity was also observed.

    日期:——
    A highly efficient metal-free aldol-type reaction of various acetals or ketals with fluorinated silyl enol ethers catalysed by less than 1 mol% HClO4 (70 wt%, aq.) is developed. This provides expedient access to a wide array of valuable fluoroalkyl ethers featuring a ketone carbonyl functionality in good to excellent yields (40 examples). Furthermore, the thus obtained adducts are readily elaborated
