Abstract

The synthesis of a library of 2,6-disubstituted-azaindoles relying on Sonogashira cross-coupling and intramolecular cyclization is described. Eleven examples of 6-alkynyl derivatives and three examples of 3-bromo-5-azaindoles are reported. One of the 3-bromo-5-azaindoles was also further functionalized with two different aryl trifluoroborate salts via Suzuki-Miyaura coupling reaction. {[}GRAPHICS] . (AU)
