  Chemoselective Radiosyntheses of Electron-Rich [¹⁸F]Fluoroarenes from Aryl(2,4,6-trimethoxyphenyl)iodonium Tosylates

  摘要：

  Hypervalent diaryliodonium salts have been used to produce various [F-18]fluoroarenes. The iodonium salt approach as a labeling precursor has been established to equally afford complex F-18-fluorinated molecules. Because of the inherent two aryl ring system connected to a central iodine atom, safeguarding the chemoselectivity during radiofluorination using diaryliodonium salts is important. Herein, we introduce a superior chemoselective radiosynthesis of [F-18]fluoroarenes using an aryl(2,4,6-trimethoxyphenyl)iodonium tosylate as a precursor for F-18-incorporation, even on electron-rich aryl rings.

  我们首先引入1,1,1,3,3,3-六氟异丙醇（HFIP）和2,2,2-三氟乙醇（TFE）作为涉及1980年代高价碘介导的酚氧化反应的独特溶剂，其中的氟代醇已经成功地将其用作反应性阳离子中间体的稳定溶剂，该反应性中间体是通过二乙酸苯基碘（III）和二碘苯基双（三氟乙酸）（PIFA）的作用而原位生成的。这项开创性的研究在高价碘化学上取得了突破，利用这种独特的培养基，出现了许多能够实现多种转化的合成应用。例如，在HFIP和TFE中首次发现了PIFA对苯醚的单电子转移（SET）氧化能力，利用独特的酸样行为来稳定芳香族阳离子自由基。最近，高价碘试剂的催化策略已发现在氟代醇的帮助下在温和条件下产生高反应性催化物种的广泛应用。氟代醇现在不仅在高价碘化学中而且在其他有机合成中也广泛用作通用溶剂。该特刊的手稿涉及高价碘化学的背景知识以及涉及氟代醇在合成二芳基碘鎓（III）盐中的应用的新话题。高价碘试剂的催

  A transition metal‐free approach for the N‐arylation of amino acid derivatives has been developed. Key to this method is the use of unsymmetric diaryliodonium salts with anisyl ligands, which proved important to obtain high chemoselectivity and yields. The scope includes the transfer of both electron deficient, electron rich and sterically hindered aryl groups with a variety of different functional
