A novel intramolecular annulation of 1-(2-alkynylphenoxy)propan-2-ones catalyzed by iron, an economical and environmentally-benign transition metal, has been developed; this new atom-economical route includes dual C–H functionalizations to construct the naphthalen-1-ol or anthracen-1-ol skeletons.

Palladium-catalyzedannulations of arynes with 2-(2-iodophenoxy)-1-substituted ethanones for the synthesis of 6H-benzo[c]chromenes are presented. This mild route allows formation of two new carbon-carbon bonds via an alpha-arylation/annulation process.
