Rh(III)-catalyzed 7-azaindole synthesis via C-H activation/annulative coupling of aminopyridines with alkynes

An efficient Rh(III)-catalyzed 7-azaindole synthesis was developed via C-H activation/annulative coupling of aminopyridines with alkynes. The reaction was highly regioselective and tolerated various functional groups, permitting the construction of various 7-azaindoles.
