A series of benzimidazole derivatives, being potent modulators of human TNFα activity, are accordingly of benefit in the treatment and/or prevention of various human ailments, including autoimmune and inflammatory disorders; neurological and neurodegenerative disorders; pain and nociceptive disorders; cardiovascular disorders; metabolic disorders; ocular disorders; and oncological disorders.
Here, a mild and general oxidative radicalrelaycarbocyclization reaction with 2‐arylbenzoimidazoles and cyclic ethers is reported. This method provides an efficient access to a wide range of structurally diverse benzimidazo[2,1‐a]isoquinoline‐6(5H)‐ones under metal‐free conditions. The wide substrate scope, good functional group tolerance, and scale‐up operation of this method are expected to promote
在这里,报道了与2-芳基苯并咪唑和环状醚的轻度和一般性氧化自由基中继碳环化反应。该方法可在无金属条件下有效地获得各种结构多样的苯并咪唑[2,1 - a ]异喹啉-6(5 H)-酮。这种方法的广泛底物范围,良好的官能团耐受性和放大操作有望促进其在生物技术和药学领域的潜在应用。

A large series of 1,2‐diaryl‐benzimidazole and 2‐aryl‐1H‐benzimidazolederivatives were synthesized with slight differences using both microwave irradiation and conventional heating methods. Usually higher yields and time reactions reduction were obtained with the former method. All compounds were assayed for their in vitro ability to inhibit humancyclooxygenases, and most of them showed an encouraging

Benzimidazoles are readily prepared from 1,2-phenylenediamine and an aldehyde using air and catalytic N-hydroxyphthalimide/Co(OAc)(2) as the oxidant. Both electron-donating and electron-withdrawing groups are tolerated.
