    Screening of antimicrobial activity of diarylamines in the 2,3,5-trimethylbenzo[b]thiophene series: a structure–activity evaluation study
    摘要:
    Gram positive (Bacillus cereus, B. subtilis), Gram negative (Pseudomonas aeruginosa, Escherichia coli) bacteria, and Candida albicans as a representative of fungi were used for screening the in vitro antimicrobial activity of diarylamines in the 2,3,5-trimethylbenzo[b]thiophene series bearing different substituents, synthesized by us using the palladium-catalyzed C-N coupling methodology. The minimal inhibitory concentration (MIC) and structure-activity relationships (SARs) were evaluated. (C) 2004 Elsevier Ltd. All rights reserved.

    摘要:
    新的甲基化噻吩并[2,3-a]和[3,2-b]咔唑(5)(R = H)的合成是通过钯催化的交叉偶联,分子内还原环化反应来实现的。通过将6-硼代甲基苯并[ b ]噻吩中间体(2)与2-溴或碘硝基苯进行Suzuki交叉偶联,得到环化前体6-((2'-硝基苯基)苯并[b]噻吩(3)。硼化中间体(2)的制备是通过溴-锂交换,然后进行硼金属转移,并使用Pd(OAc)2原位偶联,从而从6-溴苯并[ b ]硫代苯( 1)到环化前体(3)。在还原环化步骤中,还获得了N-乙基噻吩并咔唑(5)(R = Et)。为了避免形成亚磷酸三乙酯的量和反应时间,已经进行了一些实验。

    [3,2-b]carbazoles (5) (R=H) was achieved by a palladium-catalyzed cross-coupling, intramolecular reductive cyclization sequence of reactions. The cyclization precursors 6-(2′-nitrophenyl)benzo[b]thiophenes (3) were obtained by Suzuki cross-coupling of 6-boronated methylbenzo[b]thiophenes intermediates (2) with 2-bromo or iodonitrobenzene. The boronated intermediates (2) were prepared via bromine-lithium

    reaction proceeded efficiently by introduction of starting materials and reagents in a single reaction vessel. The starting materials were very easy to handle and unpleasant smell of aryl thiols that were used in conventional methods could be avoided. Novel thirty-nine benzo- and naphthothiophenes were synthesized by this method in excellent to fair yields. A four-step synthesis of benzo- and naphthothiophenes
