eye: A simple and efficient protocol for the synthesis of benzofuran and naphthofuran derivatives catalyzed by indium triflate was developed by coupling α,β‐unsaturated nitroalkenes with phenol/naphthols. The present method provides arenofuran derivatives in one pot from readily available starting materials (DCE=1,2‐dichloroethane; see scheme).
