Syntheses of indoles and quinolines based upon the Pauson-Khand reaction is described. The starting materials are an aromatic ethynylenamine and ethynylallylamine, which are obtained via Sonogashira coupling. Also. an aromatic ynamine is used for an attempt to synthesize indole.

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
