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.

Ir-Catalyzed Intramolecular Transannulation/C(sp<sup>2</sup>)–H Amination of 1,2,3,4-Tetrazoles by Electrocyclization
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 [Cp*IrCl2]2 and AgSbF6. It has been shown that the reaction proceeds via an unprecedented electrocyclization
