Biologically useful 7-azaindoles were synthesized by electrophilic cyclization of 3-alkynyl- N, N -dimethylpyridine-2-amines with molecular iodine. By this simple atom-economical approach under ambient reaction conditions, a library of interesting 3-iodo-7-azaindoles were synthesized in high yields. To synthesize the corresponding 3-bromo- and 3-chloro-7-azaindoles, an environmentally benign copper-mediated cyclization was employed, with inexpensive, nontoxic, and noncorrosive sodium chloride and sodium bromide as the sources of chlorine and bromine, respectively.
One-Pot Coupling-Cyclization-Alkylation Synthesis of 1,2,5-Trisubstituted 7-Azaindoles in a Consecutive Three-component Fashion

1,2,5-Trisubstituted 7-azaindoles are rapidly and efficiently prepared in a one-pot, copper-free alkynylation-cyclization-alkylation sequence starting from unprotected 2-aminopyridyl halides in a consecutive three-component fashion. By extension to a consecutive four-component coupling-cyclization-iodination-alkylation synthesis of 3-iodo-1-methyl-2-phenyl-1 H -pyrrolo[2,3- b ]pyridine, a concise synthesis of SIS3, a selective TGF-β1 and signaling inhibitor, was realized.

Page/Page column 144, (2010/11/30)
The present invention relates generally to processes for the chemical synthesis of azaindole and thienopyrrole compounds, in particular azaindole and thienopyrrole compounds that are substituted at the 2-position of the azaindole or thienopyrrole ring, an
A general modular method of azaindole and thienopyrrole synthesis via Pd-catalyzed tandem couplings of gem-dichloroolefins
Fang, Yuan-Qing,Yuen, Josephine,Lautens, Mark
, p. 5152 - 5160 (2008/02/07)
(Chemical Equation Presented) A palladium-catalyzed reaction of gem-dichloroolefins and a boronic acid via a tandem intramolecular C-N and intermolecular Suzuki coupling process gave corresponding substituted azaindoles or thienopyrroles. This method is a
