We describe a novel one-pot three-step reaction of 2-alkynyl arylazides through palladium-catalyzed formation of 3-hydroxy-3-phenylindolin-2-ones followed by hydrolysis of amide bonds and copper-catalyzed decarboxylation to give 2-aminobenzophenones. This synthetic method works well with various 2-alkynyl arylazides and affords the products in moderate to good yields under mild reaction conditions.

We developed a facile synthetic method to access cyclopenta[b]naphthalene derivatives via the Lewis or Br?nsted acid catalysed cascade nucleophilic addition, electronic cyclization, ring-opening rearrangement of propargylic alcohol-tethered alkylidenecyclopropanes with indole and pyrrole derivatives. The reaction exhibited a broad substrate scope and good functional group tolerance under metal-free conditions, affording the desired products in moderate to good yields.
