The introduction of sulfonyl fluoride groups into bioactive molecules can often bring about enhanced biological activity, which has attracted more research interest in chemical biology and drug development in recent years. Here, we report the development of a radical fluorosulfonylation of alkenes/intramolecular arylation cascade for the construction of chromanes with sulfonyl fluoride groups attached. The radical 1,2-fluorosulfonyl arylation reactions proceed well in both endo and exo cyclization fashions, allowing for further variation of the distance between the chromane core and the sulfonyl fluoride group.
