Abstract
We report the direct regioselective C3-functionalization of 9H-carbazoles through the C(sp2)-H insertion of α-imino rhodium(II) carbenoids generated in situ from 1-sulfonyl-1,2,3-triazoles. A variety of 1-sulfonyl-1,2,3-triazoles underwent this reaction in the presence of a rhodium(II) catalyst, and a plausible mechanism was proposed. Further regioselective C-H amination of the obtained 3-enamido carbazoles to synthesize (indol-3-yl)-9H-carbazoles, biologically valuable motifs, demonstrated the utility of this method.
