Iridium(III)-Catalyzed Regioselective C7-Amination of N-Pivaloylindoles with Sulfonoazides
摘要:
Direct C7-amination of N-pivaloylindoles has been achieved using a combination of [Cp*IrCl2](2), AgNTf2, and AgOAc as the catalyst and sulfonoazides as the nitrogen source. The reaction proceeded at room temperature to 80 degrees C to afford 7-sulfonamidoindoles in good to excellent yields. The reaction is broadly applicable to the C7-amination of a wide variety of 3-, 4-, 5-, and 6-substituted N-pivaloylindoles with either alkyl or aryl sulfonoazides.
