Various 1,2, quinolines were synthesized by palladium-catalyzed heteroannulation of 4-amino-3-iodoquinoline derivatives and internal alkynes. The 1,2,3-trisubstituted pyrrolo[3,2-c]quinolines could be further transformed by desilylation, debenzylation, or substitution.

The copper/palladium-promoted heteroannulation of terminal acetylenic compounds in the presence of resin bound ortho-hydroxy aryl iodides is described. The process produces 2-substituted benzofuran derivatives in good yield and high purity.
