Abstractmagnified imageThe bis‐oxazoline‐copper complex‐catalyzed aziridination of alkenes followed by an intramolecular Friedel–Crafts alkylation of the tethered andin situgenerated aziridine provides a one‐pot, general and efficient method for the synthesis oftrans‐2‐amino‐1‐aryltetralins from a mixture of 2‐ arylethylstyrenes (E/Z≤85:15) with excellent dia‐ stereo‐ (dr>99:1) and enantioselectivities (up to 92%ee).
