**A supramolecular metal–ligand assembly**…︁ catalyzes the [3,3]‐sigmatropic rearrangement of enammonium guests in aqueous solution. The cover picture shows the proposed catalytic cycle. The space‐restrictive host cavity forces the substrates to bind in a reactive chairlike conformation and thus acc
