A new catalytic radical system involving CoII‐based metalloradical catalysis is effective in activating sulfamoyl azides for enantioselective radical 1,6‐amination of C(sp3)−H bonds, affording six‐membered chiral heterocyclic sulfamides in high yields with excellent enantioselectivities. The CoII‐catalyzed C−H amination features an unusual degree of functional‐group tolerance and chemoselectivity. The unique reactivity and stereoselectivity is attributed to the underlying stepwise radical pathway. The resulting optically active cyclic sulfamides can be readily converted into synthetically useful chiral 1,3‐diamine derivatives without loss in enantiopurity.
