The palladium-catalyzed heteroannulation of internal alkynes using ortho-aminoiodopyridine derivatives is described. This experimentally simple procedure, which employs a Pd(dppf)Cl2/LiCl/Na2CO3 reagent system, allows rapid and reliable access to a structurally diverse range of 5-, 6- and 7-azaindoles.
