• Nickel(II)- and Silver(I)-Catalyzed C–H Bond Halogenation of Anilides and Carbamates
  作者：Ebrahim Kianmehr、Hadi Afaridoun

  DOI：10.1055/s-0040-1705972

  日期：2021.4

  ortho-C–H bond halogenation of anilides and N-aryl carbamates using easily available N-halosuccinimides (NXS) as the active halogenation reagent in the presence of nickel or silver catalyst has been developed. This method provides a new approach to 2-haloanilides and carbamates, which may serve as starting materials for the synthesis of pharmaceutically and biologically active compounds.

  日期：2010.12

  Carbazoles were successfully synthesized by oxidative cyclization of the corresponding diaryl derivatives using electrochemically generated hypervalent iodine oxidant. Electron-withdrawing nitro and donating methoxy groups at the para position of the acetamide group interfered with cyclization. Glycozoline (8) was successfully synthesized in five steps with 50% overall yield.

  Halogenated arenes are important structural motifs commonly found in biologically active molecules and used for a variety of transformations in organic synthesis. Herein, we report the mono-protected L-amino acid (L-MPAA) accelerated iridium(III) catalyzed halogenation of (hetero)anilides at room temperature. This reaction constitutes the first example of an iridium(III)/L-MPAA catalyzed general halogenation

  RhIII ] complex, bearing an acidic secondary amide moiety on the Cp ring, is able to catalyze the ortho-bromination of O-phenyl carbamates with N-bromosuccinimide (NBS) at room temperature. The presence of the acidic secondary amide moiety on the CpA ligand accelerates the bromination by the hydrogen bond between the acidic NH group of the CpA ligand and the carbonyl group of NBS.

  DOI：10.1039/c0ob00749h

  日期：——

  Treatment of various anilides with 1.5 equiv. of phenyliodine bis(trifluoroacetate) (PIFA) and 1.0 equiv. of BF3·OEt2 in AcOH at room temperature afforded the corresponding para-acetoxylated products with high regioselectivity. In addition, this reaction could be expanded to the etherification of anilides. In the presence of 2.0 equiv. of PIFA and 2.0 equiv. of BF3·OEt2, the reaction of anilides with alcohols provided the corresponding para-etherified products in good yields.
