Synthesis of 5-, 6- and 7-azaindoles via palladium-catalyzed heteroannulation of internal alkynes
The palladium-catalyzed heteroannulation of internal alkynes using orthoaminoiodopyridine derivatives is described. This experimentally simple procedure, which employs a Pd(dppf)Cl2/LiCl/Na2CO3 reagent system, allows rapid
