    A variety of substituted benzo[b]furans are readily prepared in good to excellent yields under the mild reaction conditions from o-(1-alkynylphenoxy)-1-phenylethanone under phase-transfer catalysis (PTC). This methodology accommodates simple experimental operations, inexpensive and environmentally benign catalysts, metal catalyst-free conditions, facile reagents and the possibility to conduct large-scale
    在相转移催化(PTC)下,由邻-(1-炔基苯氧基)-1-苯基乙酮在温和的反应条件下,可以容易地以良好的产率或优异的产率制备各种取代的苯并[ b ]呋喃。该方法学适用于简单的实验操作,廉价且对环境无害的催化剂,无金属催化剂的条件,简便的试剂以及进行大规模制备的可能性。通过整体结构异构化发展碳-碳键形成过程代表了最经济的方法。

    An organic superbase, phosphazene P4-(t)Bu, functioned as an active catalyst for intramolecular cyclization of o-alkynylphenyl ethers via carbon-carbon bond formation to provide an efficient synthetic method for 2,3-disubstituted benzofurans derivatives under mild reaction conditions without the need for a metal catalyst.
    有机超碱磷腈P4-(t)Bu用作通过碳-碳键形成邻炔基苯基醚分子内环化的活性催化剂,为2,3-二取代苯并呋喃衍生物的温和反应条件提供了一种有效的合成方法,而无需温和的反应条件需要金属催化剂。

    An efficient ultrasound-promoted synthesis of 2,3-disubstituted benzo[b]furans in the ionic liquid [bmim]BF4 at room temperature is reported. 5-exo-dig carbanion–yne intramolecular cyclization is mediated using anhydrous K3PO4 as a mild, inexpensive base under atmospheric conditions giving the title benzo[b]furans in excellent yields. Ionic liquid [bmim]BF4 has been used both as a reaction medium,
    据报道,在室温下,在离子液体[bmim] BF 4中超声有效地促进了2,3-二取代的苯并[ b ]呋喃的合成。在大气条件下,使用无水K 3 PO 4作为温和且廉价的碱,可以介导5 -exo-dig Carbanion-yne分子内环化反应,从而以优异的收率得到标题为benzo [ b ]呋喃的化合物。离子液体[bmim] BF 4既用作反应介质,又用作形成CC键的催化剂。

    straightforward strategy enabling access to 2,3-disubstituted benzo[b]furans. The whole synthetic process proceeds via a domino intermolecular Sonogashira coupling of 2-(2-bromophenoxy)-1-phenylethan-1-ones/alkyl 2-(2-bromophenoxy)acetates/2-(2-bromophenoxy)acetonitrile/1-(2-bromophenoxy)propan-2-one with terminal acetylenes followed by an intramolecular carbanion-yne cyclization in a 5-exo-dig manner and subsequent
    在此,我们提出了一种有效且直接的策略,能够获得 2,3-二取代苯并[ b ]呋喃。整个合成过程通过2-(2-溴苯氧基)-1-苯乙烷-1-酮/烷基 2-(2-溴苯氧基)乙酸酯/2-(2-溴苯氧基)乙腈/1-( 2-溴苯氧基)propan-2-one 与末端乙炔,然后以 5- exo - dig方式进行分子内碳负离子-炔环化,随后进行双键异构化。值得注意的是,已经以一锅法构建了两个 C-C 键,并且以良好的官能团耐受性完成了多种 (3-苄基苯并呋喃-2-基)(苯基)甲酮。
  • tert-BuOK-mediated carbanion–yne intramolecular cyclization: synthesis of 2-substituted 3-benzylbenzofurans
    作者:Po-Yuan Chen、Tzu-Pin Wang、Keng-Shiang Huang、Chai-Lin Kao、Jui-Chi Tsai、Eng-Chi Wang
    DOI:10.1016/j.tet.2011.09.144
    日期:2011.12
    A mild, efficient, and regioselective carbanion-yne intramolecular cyclization mediated by t-BuOK for the synthesis of 2-substituted 3-benzylbenzofurans is developed. It was started from o-iodophenol (1), based on O-alkylation, and the Sonogashira reaction in sequence to produce 2-(2-phenylethynyl-phenoxy)-1-arylalkanones (5). An intramolecular carbanion-yne 5-exo-dig cyclization reaction of 5, which was mediated by t-BuOK, yielded title benzofurans in good yields. (C) 2011 Elsevier Ltd. All rights reserved.
