Fe(OTf)3- and γ-Cyclodextrin-Catalyzed Hydroamination of Alkenes with Carbazoles.

A Fe(OTf)3- and γ-cyclodextrin catalyzed hydroamination of alkenes with carbazoles is demonstrated. This biomimetic-catalyst-oriented sustainable and green method could deliver a wide scope of N-alkylated carbazoles and N-alkylated-carbazole-fused aromatics in up to 97% yield. The salient features of this transformation include simple and benign reaction conditions with no need for a strong base, additive, or the irradiation of light.
