The first syntheses of privileged [5,6]‐bicyclic heterocycles, with ring‐junction nitrogen atoms, by transition metal catalyzed C−H functionalization of C‐alkenyl azoles is disclosed. Several reactions are applied to alkenyl imidazoles, pyrazoles, and triazoles to provide products with nitrogen incorporated at different sites. Alkyne and diazoketone coupling partners give azolopyridines with various
