cyclotrimerization and crossenynemetathesis. The cyclotrimerization reaction of phenylacetylene catalyzed by [RuCl2(p-cymene)]2 can be switched to enynemetathesis by the introduction of a sterically hindered N-heterocyclic carbene. The 1,3-diene formed during this reaction reacts with dienophiles to form the Diels–Alder adduct. A practical one-pot synthesis method, utilizing enynemetathesis/Diels–Alder reactions
