Copper‐Catalyzed Intramolecular C–H Amination

Abstract The amino‐functionalization of tertiary, secondary and benzylic C–H bonds of tethered carbamates and sulfamates by iodosobenzene is catalyzed by CuI‐diimine complexes in moderate to good yield. Employing homochiral imine‐Cucatalysts affords oxazolidinones and oxathiazinanes with modest enantioselectivity.
