I want to ride my azacycle: The title reaction of enynamides affords a wide diversity of azacycles. The reactions are high‐yielding, highly stereoselective, and proceed rapidly under mild reaction conditions. Equivalent transformations using enynhydrazides offer new routes to pyrazole and indazole scaffolds.

Syntheses of pyridazine and pyrrole analogues of 2‐aminotetralin starting from 3‐cyclohexene‐1‐carboxylic acid are reported. All syntheses involve the following key steps: Curtius rearrangement for amine functionality, inverse electron demand Diels–Alder addition with 1,2,4,5‐tetrazine for pyridazine ring synthesis, and pyridazine‐to‐pyrrole ring contraction for pyrrole ring formation.
