  • Copper(II)-Catalyzed Oxidative Cross-Coupling of Anilines, Primary Alkyl Amines, and Sodium Azide Using TBHP: A Route to 2-Substituted Benzimidazoles
    作者:Devulapally Mahesh、Pradeep Sadhu、Tharmalingam Punniyamurthy
    DOI:10.1021/acs.joc.6b00186
    日期:2016.4.15
    Copper(II)-catalyzed oxidative cross-coupling of anilines, primary alkyl amines, and sodium azide is described in the presence of TBHP at moderate temperature. This one-pot multicomponent protocol involves a domino C–H functionalization, transimination, ortho-selective amination, and a cyclization sequence. The broad substrate scope and functional group compatibility are the significant practical features

    elemental mapping. The obtained materials exhibit high surface area and a narrow distribution of mesoporosity. The catalytic performance of the Yb@l–MSNs was tested by synthesis of 1,2‐disubstituted benzimidazoles and 2‐substituted benzimidazoles through the coupling of aldehydes with o‐phenylenediamine. The catalyst resulted in excellent yields in short reaction times and the reaction showed tolerance toward
    苯并咪唑环是当代药物发现中的重要药效团。因此,近年来,鉴定含苯并咪唑支架的新化合物的努力已引起广泛关注。在本研究中,大孔MCM-41型中孔二氧化硅(l‐MSN)负载的已通过湿浸渍法成功制备。在稀土属盐中,三氟甲磺酸已被广泛研究为有机合成中的催化剂,但毒性较低的氧化尚待探索。相对于许多催化活性属(例如Pd,Au,Ru,Ir,Pt)而言,high的含量较高且成本较低,这为开发可持续的有机转化催化剂提供了机会。该催化剂已通过多种技术进行了表征,包括氮吸附,FT-IR,TEMSEM,EDX技术和元素图谱。所获得的材料表现出高的表面积和中孔的窄分布。Yb @ l的催化性能通过醛与邻苯二胺的偶联合成1,2-二取代的苯并咪唑和2-取代的苯并咪唑来测试–MSN 。该催化剂在较短的反应时间内获得了优异的收率,并且该反应在室温下显示出对给电子和吸电子官能团的耐受性。一个特别有趣的发现是该反应的溶剂选择性。也就是说,在-乙醇中主要生成1

  • N-Chlorosuccinimide/Sodium Hydroxide-Mediated Synthesis of Benzimidazoles from Amidines under Mild Conditions
    作者:Thanh Binh Nguyen、Ali Al-Mourabit、Ludmila Ermolenko
    DOI:10.3987/com-12-s(n)53

    A convenient room-temperature one-pot procedure for the preparation of benzimidazoles derivatives from N-arylamidines has been developed. The reaction of N-aryl-N'-chloro amidines, generated by the treatment of N-arylamidines with N-chlorosuccinimide, in presence of sodium hydroxide provides benzimidazoles in good to excellent yields. Nitrogen anion generated in situ from succinimide (by-product of the chlorination step using NCS) and hydroxide anion was found to be highly effective as Bronsted base to promote the cyclization into benzimidazole of N-aryl-N'-chloroamidine.
