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.
