, p. 5355 - 5358 (1998)
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

To facilitate precatalyst recovery and reuse, we have developed a fluorous, oxime-based palladacycle 1 and demonstrated that it is a very efficient and versatile precatalyst for carbo- and heteroannulation of internal alkynes with functionalized aryl halides in aqueous medium. A uniform reaction condition for these annulation reactions was also developed.
Palladium-catalyzed synthesis of 2,3-disubstituted 5-azaindoles via heteroannulation reaction and of 2-substituted 5-azaindoles through domino sila-Sonogashira/5-endo cyclization
Livecchi, Marion,Calvet, Geraldine,Schmidt, Frederic
, p. 5006 - 5016 (2012/07/03)
A general and efficient procedure for the synthesis of 2,3-disubstituted 5-azaindoles through the palladium-catalyzed heteroannulation of 4-acetamido-3-iodopyridines and diaryl-, dialkyl-, or arylalkylalkynes is described along with a study of the reactio
Synthesis of polysubstituted 5-azaindoles via palladium-catalyzed heteroannulation of diarylalkynes
Calvet, Geraldine,Livecchi, Marion,Schmidt, Frederic
experimental part, p. 4734 - 4740 (2011/07/08)
A general and efficient procedure for the synthesis of functionalized 5-azaindoles through the catalyzed heteroannulation of 4-acetamido-3- iodopyridines and diarylalkynes is described. The reaction allows the preparation of a variety of substituted 2,3-d
