Abstract

Synthesis of 5-, 6-, and 7-Azaindoles via Palladium-Catalyzed Heteroannulation of Internal Alkynes.-The Pd-catalyzed heteroannulation of internal alkynes (II) using various ortho-aminoiodopyridines allows a rapid access to a structurally diverse range of azaindoles. - (UJJAINWALLA, F.; WARNER, D.; Tetrahedron Lett. 39 (1998) 30, 5355-5358; Dep.
