    镍催化的腈与芳族腈的偶联
    摘要:
    该手稿描述了Ni催化的唑类化合物与芳族腈的偶联。BPh 3的使用可促进电子形式多样的唑和苄腈的这些芳基化。尽管镍催化剂对于苯基恶唑的芳基化是必需的,但是即使在不存在Ni催化剂的情况下,苯并恶唑与某些腈的芳基化也可以提供芳基化的产物,尽管收率比催化方法低。与未催化的转化相比,镍催化的方法显示出更高的速率和更广阔的范围。

  • Direct Oxidative C–H Arylation of Benzoxazoles with Arylsulfonyl Hydrazides Promoted by Palladium Complexes
    作者:Fuk Kwong、On Yuen、Chau So、Wing Wong
    DOI:10.1055/s-0032-1317350
    日期:——
    This study describes a direct oxidative C-2 arylation of benzoxazoles using arylsulfonyl hydrazides as the aryl sources. A simple catalyst system [Pd(OAc)2 and Ph3P] allows the reactions to proceed smoothly under oxidative reaction conditions. Other ­heteroarenes such as caffeine and benzothiazole are also applicable substrates. Notably, this catalytic system tolerates halogen substituents which provides
    本研究描述了使用芳基磺酰作为芳基来源的苯并恶唑的直接氧化 C-2 芳基化。一个简单的催化剂体系 [Pd(OAc)2 和 Ph3P] 使反应在氧化反应条件下顺利进行。其他杂芳烃咖啡因苯并噻唑也是适用的底物。值得注意的是,该催化体系耐受卤素取代基,这为当前使用芳基卤化物的交叉偶联反应提供了有用的补充。
  • p -Toluenesulfonic acid-catalyzed metal-free formal [4 + 1] heteroannulation via N H/O H/S H functionalization: One-pot access to 2-aryl/hetaryl/alkyl benzazole derivatives
    作者:Abhijeet Srivastava、Gaurav Shukla、Maya Shankar Singh
    DOI:10.1016/j.tet.2016.12.073
    日期:2017.2
    concise and direct one-pot [4 + 1] synthetic strategy for the construction of 2-substituted benzazoles such as benzoxazoles and benzothiazoles has been disclosed in high yields (80–98%) by cascade coupling reaction of 2-amino(thio)phenols with β-oxodithioesters. The current approach enables NH/OH/SH functionalization in one-pot under solventless condition leading to diverse benzazoles without use of any
    通过2-基(代)的级联偶联反应,已公开了一种高产率(80-98%)的简洁,直接的一锅[4 +1]合成策略,用于构建2-取代的苯并唑,如苯并恶唑苯并噻唑与β-氧二代酯。目前的方法可以在无溶剂条件下在一锅中实现N H / O H / S H官能化,从而无需使用任何外部属即可产生多种苯并恶唑。各种各样的2-基(代)和β-氧二代酯均具有出色的官能团耐受性,可用于该转化。此外,我们通过证明其与DNA拓扑异构酶II抑制剂的多样化多样化的相容性,抢占了这一新策略的广泛含义。
