has been described by Takahashi (Scheme 1a, eq 2).4a Zhou recently reported the synthesis of a little number of ullazines by Rh(III)-catalyzed oxidative annulation of pyrroloquinolines with diphenylacetylene5 based on early described Dong/Chen's conditions for single C−H activation/oxidative annulation of N-arylpyrroles to pyrroloquinolines (Scheme 1a, eq 3).6 It is worth to mention that an excess of
