Tandem radical cyclisations of aminyl radicals generated from sulfenamide precursors have been used for the synthesis of pyrrolizidines and other polycyclic nitrogen heterocycles. The aminyl radicals are generated by reaction between sulfenamide precursors and Bu3SnH.

Sulfenamides are synthesised from reaction between amines and N-(benzenesulfenyl)-phthalimide or benzenesulfenyl chloride. The sulfenamides undergo reaction with tributyltin hydride to yield aminylradicals which can be cyclised onto suitable alkenes.
