 Metal-free intramolecular oxidative cyclizations of sulfonamido- and hydroxyalkenes have been developed. Reactions employ hypervalent iodine (III) as oxidant and a strong Bronsted acid as promoter. Changing the Bronsted acid allows for incorporation of fluoride or nitrogen-containing groups, resulting in the formation of fluoroamines, fluoroethers and diamines.
