A direct asymmetric dearomative amination of tryptamines with O‐(2,4‐dinitrophenyl)hydroxylamine (DPH) was achieved using CuBr‐bisoxazoline complex as a catalyst, affording 3a‐amino‐pyrroloindolines in good to excellent enantioselectivity under mild reaction conditions. Furthermore, the synthetic value of this method was demonstrated in the total synthesis of (−)‐psychotriasine in a highly concise manner.
