Synthesis of N-aryl-3-(arylimino)-3H-indo1-2-amines via hypervalent iodine promoted oxidative diamination of indoles
A direct and fast oxidative diamination of substituted indoles with anilines was realized by using 1-fluoro-1,2-benziodoxol-3(1H)-one under mild conditions. This protocol could provide a wide range of synthetically valuable N-aryl-3-(arylimino)-3H-indol-2-amine derivatives under peroxide-free conditions within 30 min in up to 91% yields.
