Résumé/Abstract Intramolecular Michael addition of β-ketoesters on enones 1, 2 and 3 with two conjugated unsaturations along the connecting chain led to cyclic monomers and dimers. These reactions work best with a cis alkene; they give poor yield of monomer with a trans alkene and no monomer with an alkyne.
