  Rh[III]-Catalyzed C–H Amidation Using Aroyloxycarbamates To Give N-Boc Protected Arylamines

  摘要：

  The Rh(III)-catalyzed amidation of C(sp(2))-H bonds by the use of electron-deficient aroyloxycarbamates as efficient electrophilic amidation partners is reported. The reaction proceeded under mild conditions with broad functional group tolerance, and pyridine and O-methyl hydroxamic acids serve as efficient directing groups, giving access to valuable N-Boc protected arylamines (also Fmoc and Cbz). Preliminary mechanistic experiments are discussed.

  [RhCp*Cl₂]₂-Catalyzed Directed N-Boc Amidation of Arenes “on Water”

  摘要：

  Rhodium(III) catalysis on water is effective for directed C-H amidation of arenes. The catalytic process is promoted by OH groups present on the hydrophobic water surface and is inefficient in all (most) common organic solvents investigated so far. In the presence of easily prepared tert-butyl 2,4-dinitrophenoxycarbamate, a new and stable nitrene source, the on water reaction can efficiently provide the desired N-Boc-aminated products with good functional group tolerance.

  The aryne [3 + 2] cycloaddition process with pyridinium imides breaks the aromaticity of the pyridine ring. By equipping the imide nitrogen with a sulfonyl group, the intermediate readily eliminates a sulfinate anion to restore the aromaticity, leading to the formation of pyrido[1,2-b]indazoles. The scope and limitation of this reaction are discussed. As an extension of this chemistry, N-tosylisoquinolinium
