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

N-(3,5-Hexadienoyl)-acrylimidates, which have been synthesized by acylation of 2-ethoxy-1-aza-1,3-butadienes with 3,5-hexadienoyl chloride, are found to undergo facile Intramolecular Diels-Alder cycloadditions to afford predominately cis-hexahydroisoquinolines in good yields.
