First, syntheses of pyrrole-fused derivatives via domino C-C/C-N coupling of ortho-dihaloarenes with imines were accomplished. Employment of ortho-dihaloarenes for sequential regioselective Suzuki reaction/double C-N coupling afforded corresponding indole-fused structures. Finally, syntheses of previously unexplored phenanthridine-fused architectures by regioselective Sonogashira reaction followed by domino or one-pot C-N coupling/hydroamination/C-H arylation were described.
