  C-S coupling with nitro group as leaving group via simple inorganic salt catalysis

  摘要：

  An efficient and practical synthetic protocol to synthesize nonsymmetrical aryl thioethers by nucleophilic aromatic substitution (SNAr) reaction of nitroarenes by thiols with potassium phosphate as the catalyst is described. Various moderate to strong electron-withdrawing functional groups are tolerated by the system to provide thioethers in a good to excellent yields. We also showed that the present method allows access to 3 drug examples in a short reaction time. Finally, mechanistic studies suggest that the reaction may form the classic Meisenheimer complex through a two-step addition elimination mechanism.

  Provided is a simple and efficient production process of a nucleobase having a perfluoroalkyl group. A nucleobase (for example, uracils, cytosines, adenines, guanines, hypoxanthines, xanthines, or the like) is reacted with a perfluoroalkyl halide in the presence of a sulfoxide, a peroxide and an iron compound to produce a perfluoroalkyl-substituted nucleobase, which is useful as an intermediate for medical drugs, economically.

  提供一种具有全氟烷基的核碱的简单高效的生产工艺。将核碱（例如尿嘧啶、胞嘧啶、腺嘌呤、鸟嘌呤、次黄嘌呤、黄嘌呤等）与全氟烷基卤化物在亚砜、过氧化物和铁化合物的存在下反应，制得全氟烷基取代的核碱，该中间体在医药制剂中具有经济价值。
