    摘要:
    通过在钯催化剂的存在下,将末端乙炔与市售的邻-碘硫代苯甲醚偶联,然后对所得的邻-(1-炔基)硫代苯甲醚衍生物进行亲电环化反应,已以高收率制备了2,3-二取代的苯并[b]噻吩。I(2),Br(2),NBS,pO(2)NC(6)H(4)SCl和PhSeCl已被用作亲电子试剂。芳基,乙烯基和烷基取代的末端乙炔经过这种偶联和环化反应,可产生优异的苯并[b]噻吩收率。(三甲基甲硅烷基)乙炔也与I(2),NBS以及硫和硒亲电试剂进行这种偶联/环化过程,得到相应的2-(三甲基甲硅烷基)苯并[b]噻吩。但是,使用Br(2)对含甲硅烷基的硫代苯甲醚环化,可得到2,3-二溴苯并[b]噻吩。

    alkyl-substituted terminal acetylenes undergo this coupling and cyclization to produce excellent yields of benzo[b]thiophenes. (Trimethylsilyl)acetylene also undergoes this coupling/cyclization process with I(2), NBS, and the sulfur and selenium electrophiles to afford the corresponding 2-(trimethylsilyl)benzo[b]thiophenes. However, cyclization of the silyl-containing thioanisole using Br(2) affords

    A stable dimethyl(thiodimethyl)sulfonium tetrafluoroborate salt was employed for the electrophilic cyclization reaction of o-alkynyl thioanisoles for the synthesis of 2,3-disubstituted benzo[b]thiophenes. The reaction described herein works well with various substituted alkynes in excellent yields, and a valuable thiomethyl group was introduced with ease.

    We have developed a greener process for the synthesis of 2,3-disubstituted benzo[b]thiophenes using electrophilic cyclization as a key step. Our method not only employs an environmentally friendly solvent ethanol, but also utilizes safe and inexpensive inorganic reagents to furnish the desired products in high yields under mild reaction conditions. In addition to iodo- and bromocyclization, chlorocylization was also successfully accomplished. (c) 2013 Elsevier Ltd. All rights reserved.
  • Green synthesis of benzo[b]thiophenes via iron(III) mediated 5-endo-dig iodocyclization of 2-alkynylthioanisoles

    A reaction of iron(III) chloride with sodium iodide was used to generate iodine for an innovative take on electrophilic cyclization. With ethanol as solvent, the reaction was observed to provide ideal conditions for iodocyclization of 2-alkynylthioanisoles. The fundamental step allows formation of iodine which becomes free to undergo reaction with the starting alkyne to yield the cyclized product. Implementing environmentally benign and simple chemistry, 2-iodosubstituted benzo[b]thiophenes were synthesized in high yields to produce an interesting display of useful molecules.

    A convenient methodology for the synthesis of mono- and di-halogenated benzo[b]thiophenes is described herein, which utilizes copper(II) sulfate pentahydrate and various sodium halides in the presence of substituted 2-alkynylthioanisoles. The proposed method is facile, uses ethanol as a green solvent, and results in uniquely substituted benzo[b]thiophene structures with isolated yields up to 96%. The
    本文描述了合成单和二卤代苯并[b]噻吩的简便方法,该方法在取代的2-炔基硫代苯甲醚存在下利用五水合硫酸铜(II)和各种卤化钠。所提出的方法简便易行,使用乙醇作为绿色溶剂,并能产生独特取代的苯并[b]噻吩结构,分离产率高达96%。该方法最有用的组成部分是在苯并[b]噻吩环周围的每个可用位置(2-7)处选择性引入溴原子,同时使位置3保留在特定的卤素原子(例如Cl,Br或I)上。芳香族卤素是有用的反应性处理剂。因此,在特定位置选择性引入卤素对于通过金属催化的交叉偶联反应有针对性地合成生物活性分子和复杂的有机材料具有重要意义。这项工作是一种合成二卤代苯并[b]噻吩核心结构的新颖方法,为本文讨论的当前方法提供了一种出色的替代方法。
