elimination of readily accessible 6‐silylcyclohexene‐1‐triflates allows the mild, chemoselective, and functional‐group tolerant generation of cyclic allene intermediates, which undergo efficient trapping reactions with stable 1,3‐dipoles. The reactions proceed with high levels of both regio‐ and diastereoselectivity. The reaction of cyclic allenes with azides is accompanied by the facile loss of dinitrogen
