An efficient strategy for the intramolecular denitrogenative transannulation/C(sp2)-H amination of 1,2,3,4-tetrazoles bearing C8-substituted arenes, heteroarenes, and alkenes is described. The process involves the generation of the metal-nitrene intermediate from tetrazole by the combination of [CpIrCl2]2 and AgSbF6. It has been shown that the reaction proceeds via an unprecedented electrocyclization process. The method has been successfully applied for the synthesis of a diverse array of α-carbolines and 7-azaindoles.

Abstract 2-Substituted 7-azaindoles are rapidly and efficiently prepared in a one-pot copper-free alkynylation-cyclization sequence starting from 2-aminopyridyl halides and terminal alkynes. Most importantly the amino nitrogen atom neither requires activation nor protection throughout the sequence.
