An iron‐catalyzedcycloisomerization of allenols to deoxygenated pyranose glycals has been developed. Combinedexperimental and computationalstudies show that the iron complex exhibits a dual catalytic role in that the non‐innocent cyclopentadienone ligand acts as proton shuttle by initial hydrogen abstraction from the alcohol and by facilitating protonation and deprotonation events in the isomerization
