Key Points

Furoindoles are synthesized effectively through Rh(II)-catalyzed cyclopropenation reactions.
The method utilizes 3-diazooxindoles and electron-rich arylacetylenes, revealing significant synthetic versatility.
In situ rearrangement following cyclopropenation leads to the desired fully aromatic furoindoles.
This transformation showcases unprecedented activation mechanisms, paving the way for new approaches in organic synthesis.
