Enynes connected through aromatic rings are used as substrates for metathesis reactions. The reactivity of three ruthenium carbene complexes is compared. The resulting 1,3-dienes are suitable precursors of polycyclic structures via a Diels−Alder process. Some domino RCM-Diels−Alder reactions are performed, suggesting a possible beneficial effect of the ruthenium catalyst in the cycloaddition process
