• FACILE CONVERSION OF 1,3-DISUBSTITUTED THIOUREAS TO THE CORRESPONDING UREAS BY SUPEROXIDE RADICAL ANION (O₂^·−) IN DIMETHYL SULFOXIDE
  作者：Yong Hae Kim、Gyu Hwan Yon、Hyung Jin Kim

  DOI：10.1246/cl.1984.309

  日期：1984.3.5

  Treatment of 1,3-disubstituted thioureas with superoxide radical anion (O2·−) at 20 °C in dimethyl sulfoxide resulted in the formation of 1,3-disubstituted ureas in excellent yields. The desulfurization appears to proceed by the formation of peroxy-sulfur intermediates such as peroxy-sulfenate, -sulfinate and/or -sulfonate.

  作者：Takehiko Yoshimitsu、Kenichi Matsuda、Hiroto Nagaoka、Koji Tsukamoto、Tetsuaki Tanaka

  DOI：10.1021/ol7023295

  日期：2007.11.1

  A new carbamoylation of tertiary amines is reported. This rare C-H transformation features the direct generation of alpha-aminoalkyl radicals from tertiary amines, followed by the addition of the resultant nucleophilic radicals to isocyanates, enabling unique access to N,N-dialkylated amino acid derivatives. The authors put forward a mechanistic proposal that is based on the isolation of borinamides

  据报道，叔胺有新的氨基甲酰化作用。这种罕见的CH转化具有从叔胺直接生成α-氨基烷基的特征，然后将所得的亲核基团添加到异氰酸酯中，从而可以唯一地获得N，N-二烷基化的氨基酸衍生物。作者提出了一种机制建议，该建议基于分离通过用Et3B捕获氮自由基中间体而产生的硼酰胺的方法。本转化提供了一种从容易获得的材料生产甲哌卡因的新的一步法，这种药物是临床上重要的局部麻醉药。
• A Novel C-N Migration Rearrangement Based on N-F Compounds for the Synthesis of <i>N</i> -Alkyl Diaryl Ureas
  作者：Yi-Xiao Zhao、Tian Xie、San-Ke Yang、Xian-Jin Yang

  DOI：10.1002/ejoc.201901602

  日期：2020.1.31

  A novel aryl C–N shift rearrangement reaction to form alkyl diaryl ureas from facilely available FPSBA derivatives was developed. FPSBA selectively reacted with secondary alkyl phenylamines to afford unsymmetrical alkyl diaryl ureas in good yields through a vicinal SN2′ mechanism rather than the traditional isocyanate intermediate pathway.

  Thiocarbonyl compounds such as substituted-thioureas, -thioamides and -thiocarbamates were found to react with a peroxysulfur intermediate (3) which is generated by the treatment of 2-nitrobenzenesulfonyl chloride with potassium superoxide to convert into the corresponding carbonyl compounds in quantitative yield at −30°C in acetonitrile.

  (TFE) promoted synthesis of unsymmetric ureas was described. This approach enabled the construction of a variety of ureas from the readily prepared and easy-to-handle dioxazolones and amines via tandem Lossen rearrangement/condensation process.
