A novel A21-CuI catalyzed direct nitrogenation of biphenyl halides for the direct synthesis of carbazoles via a direct C-H amination process has been developed. A recyclable and inexpensive Cu-catalyst was successfully employed in N-heterocyclic compound synthesis via tandem azidation and C-H amination, which makes this protocol very practical and easy to handle.
Photo-Fries rearrangement of carbazol-2-yl sulfonates: Efficient tool for the introduction of sulfonyl groups into polycyclic aromatic compounds

Systematic studies on the photo-Fries rearrangement of different 9H-carbazol-2-yl sulfonates 2 have shown that this type of conversion can be readily used for the preparative-scale introduction of alkyl- or arylsulfonyl groups into polycyclic aromatic compounds under very mild conditions. A series of new 1-sulfonyl- (3) or 3-sulfonyl-9H-carbazoles (4) were prepared in medium-to-good yields, and characterized by UV/VIS, 1H-NMR, and 13C-NMR spectroscopy, as well as by elemental analysis. Effects of irradiation wavelength, solvent polarity, presence or absence of O2, and photosensitizers were studied in detail.
Diels-Alder reactions of 2- and 3-nitroindoles. A simple hydroxycarbazole synthesis
Kishbaugh, Tara L.S,Gribble, Gordon W

A Diels-Alder reaction of 3- and 2-nitroindoles with Danishefsky's diene gives the expected 2- and 3-hydroxycarbazoles in very good to excellent yields (73-91%) and with apparent complete regioselectivity.
