An one-pot reaction for the rapid construction of tricyclic fused indoline frameworks from 2-aryl indoles and N-acetyl enamides under oxygen atmosphere has been developed. The notable features of this method involve easy availability of starting materials, simple manipulation, good regio- and diastereo-selectivity, as well as environmentally friendly conditions. Mechanistic studies indicated that this reaction proceeds via oxidative dearomatization and subsequent [3+2] annulation with enamides.

Key words: cobalt-catalysis, oxidative dearomatization, annulation, indoles, enamides
