Substituent-Controllable Cascade Regioselective Annulation of <i>β</i>-Enaminones with <i>N</i>-Sulfonyl Triazoles for Modular Access to Imidazoles and Pyrroles

A controllable synthesis of trisubstituted imidazoles and pyrroles has been developed through rhodium(II)-catalyzed regioselective annulation of <i>N</i>-sulfonyl-1,2,3-trizaoles with <i>β</i>-enaminones. The imidazole ring was formed through a 1,1-insertion of the N-H bond to α-imino rhodium carben...
