The palladium catalyzed tandem cyclization/coupling  reaction of conjugated enynes having a stabilizing carbon nucleophile with  unsaturated halides or triflate afforded stereodefined functionalized  1,3-bis-exocyclic dienes. Moderate yields were obtained with substrates  of type 1. However, higher homologs of  type 2 led to the formation of functionalized  1,3-bis-exocyclic dienes and hexatrienes in good yields. An initial  study on the sequential cyclization/coupling reaction/electrocyclization  in a one-pot procedure leading to cyclohexadienes is also presented.
