Iron‐catalyzed intramolecular hydroalkoxylation reactions of allenes were performed to provide various tetrahydrofurans by regioselective 5‐exo cyclization pathway, as the Lewis acidic activation of Fe(III) salts toward unsaturated CC bonds, allenes and alkenes. Cyclohexyl substituted allenes especially isomerized to dienes at a rapid rate, which underwent a competing 6‐endo cyclization mode. The
