Abstract
Both azido (N 3 ) and trifluoromethyl (CF 3 ) groups are key moieties of numerous valuable molecules that are extensively applied in drug discovery, chemical biology, and synthetic chemistry. However, the asymmetric construction of chiral quaternary stereocenters bearing both N 3 and CF 3 groups is still unexplored. Herein, we report a kind of bench-stable and easily adjustable benziodazolone-based azidating reagents. These reagents were used to achieve an enantioselective copper-catalyzed azidation of N -unprotected 3-trifluoromethylated oxindoles to provide diverse enantioenriched 3-N 3 -3-CF 3 oxindoles.
