The palladium-catalyzed cycloisomerization of acyclic bisdienes to cyclized enedienes defines a novel strategy for the stereoselective cyclization of certain unsymmetric bisdiene substrates to form functionalized five- and six-membered rings. The full details of our investigation into this novel cycloisomerization, including our observations on substrate requirements, stereoselectivity, the influence
