  钯或铜催化芳基卤化物的胺化或酰胺化以及分子内环化反应生成硫代咔唑的新颖合成路线

  摘要：

  进行钯或铜催化的胺化或酰胺化反应以获得噻吩并咔唑的二芳基胺和二芳基乙酰胺前体。在已知邻位卤代二苯胺的咔唑条件下，邻溴二芳基胺未环化为相应的噻吩并咔唑的事实使我们获得了一种钯催化的分子内环化反应的高效方法，其中邻卤代二芳基乙酰胺N脱保护为噻吩并咔唑。基于由Cu（OAc）2形成的Pd（0）的再氧化避免二芳基胺分子内环化的其他方法，避免使用化学计量的Pd（OAc）2得到适量产率的噻吩并咔唑，包括环A甲氧基化化合物。尝试在胺化和分子内环化的“一锅法”反应中结合钯和铜催化剂，以低收率得到N-苯并[ b ]噻吩取代的咔唑和所需的噻吩并咔唑作为主要产物。

  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.

  New ortho-bromodiarylamines in the benzo[b]thiophene series were prepared by palladium-catalyzed amination, either in the benzene or in the thiophene ring. These were submitted to palladium-catalyzed cyclization, under different required conditions, to give several differently substituted thieno[3,2-c] or [2,3-b]carbazoles and indolo[3,2-b]benzo[b]thiophenes. This constitutes a novel synthetic route

  通过钯催化的胺化反应，可以在苯或噻吩环中制备苯并[ b ]噻吩系列的新邻溴二芳基胺。将它们在不同的条件下进行钯催化的环化反应，得到几种不同取代的噻吩并[3,2- c ]或[2,3- b ]咔唑和吲哚并[3,2- b ]苯并[ b ]噻吩。这构成了通往两个四环系统的新颖合成途径。
• Synthesis of diarylamines in the benzo[b]thiophene series bearing electron donating or withdrawing groups by Buchwald–Hartwig C–N coupling

  Diarylamines in the benzo[b]thiophene series bearing electron donating or withdrawing groups, were prepared by Buchwald-Hartwig C-N coupling in moderate to high yields. The conditions used were Pd(OAc)(2) (3 mol%), BINAP as ligand (4 mol%) and Cs2Co3 as base (1.4 equiv.), in toluene at 100degreesC, being 6-bromo or amino benzo[b]thiophenes coupled, respectively, with substituted anilines or phenylbromides. The 6-aminobenzo[b]thiophene derivatives were also prepared by palladium catalyzed C-N coupling of the corresponding 6-bromo compounds with benzophenone imine, followed by acidic hydrolysis of the imino derivatives. When 4-nitrobromobenzene and 4-bromobenzonitrile were used as coupling components, triarylamines were also isolated in small amounts. The presence of a fluorine atom on the phenylbromide highly increases the diarylamine yields. (C) 2003 Elsevier Science Ltd. All rights reserved.
