  • Synthesis of 3-Trifluoromethylbenzo[<i>b</i>]furans from Phenols via Direct <i>Ortho</i> Functionalization by Extended Pummerer Reaction
    作者:Takayuki Kobatake、Daishi Fujino、Suguru Yoshida、Hideki Yorimitsu、Koichiro Oshima
    DOI:10.1021/ja1030134
    日期:2010.9.1
    diversity-oriented route to trifluoromethylbenzo[b]furans has been devised. A variety of phenols are directly converted to the corresponding 2-methylthio-3-trifluoromethylbenzo[b]furans by new triflic-anhydride-mediated extended Pummerer annulation reactions with trifluoromethylketene dithioacetal monoxide. The methylthio group of the products undergoes further transformations, which increase the diversity
    已经设计了一种简洁且面向多样性的三氟甲基苯并 [b] 呋喃路线。通过新的三氟甲磺酸酐介导的延长 Pummerer 环化反应与三氟甲基乙烯酮二硫代乙缩醛一氧化物,多种酚类直接转化为相应的 2-甲硫基-3-三氟甲基苯并 [b] 呋喃。产物的甲硫基经过进一步的转变,增加了可用三氟甲基苯并[b]呋喃的多样性。
  • A first regioselective synthesis of 3-fluoroalkylated benzofurans via palladium-catalyzed annulation of fluorine-containing internal alkynes with variously substituted 2-iodophenol
    作者:Tsutomu Konno、Jungha Chae、Takashi Ishihara、Hiroki Yamanaka
    DOI:10.1016/j.tet.2004.10.005
    日期:2004.12
    The palladium-catalyzed annulation reaction of a variety of fluorine-containing internal alkynes with 2-iodophenol derivatives was investigated. The use of P(t-Bu)3 as a ligand on palladium was found to be crucial in this annulation reaction, resulting in the exclusive formation of 3-fluoroalkylated benzofurans in high yields. 19F NMR analysis of the reaction mixture revealed that the addition of phenol
    研究了各种含氟内炔与2-碘苯酚衍生物的钯催化的环化反应。已发现使用P(t- Bu)3作为钯上的配体在该环化反应中至关重要,从而导致以高收率独家形成3-氟烷基化的苯并呋喃。反应混合物的19 F NMR分析表明,将苯酚加入到氟代烷基化的炔烃中,随后进行分子内Heck反应,得到相应的3-氟代烷基化的苯并呋喃。
  • Synthesis of 3-Trifluoromethylbenzofurans via Palladium-Catalyzed Tandem Elimination/Annulation of β-Chloro-β-(trifluoromethyl)styrenes with 2-Halophenols
    作者:Lian-Hui Chen、Xing-Guo Zhang、Chong Wang、Chen-Liang Deng
    DOI:10.1055/s-0033-1338560
    日期:——
    A palladium-catalyzed tandem elimination and annulation reaction has been developed. In this way, a variety of 3-trifluoromethybenzofurans were prepared in moderate to good yields via tandem reaction of beta-chloro-beta-(trifluoromethyl)styrenes with 2-iodophenols and 2-bromophenols.
  • One-pot synthesis of 3-trifluoromethylbenzofurans via tandem iodocyclization and trifluoromethylation of 2-alkynylanisoles

    日期:2014.2
    A two-step, one-pot tandem iodocyclization and trifluoromethylation have been developed. A variety of 3-trifluoromethylbenzofurans were prepared in moderate to good yields via the tandem reaction of 2-alkynylanisoles with elemental iodine and (trifluoromethyl)trimethylsilane.
