Acetylenic vinyllithiums, generated by low-temperature metal-halogen exchange, were found to undergo facile 5-exo-dig cyclization to afford isomerically pure conjugated 1,3-bis-exocyclic dienes which serve as reactive precursors to complex polycyclic materials through subsequent Diels-Alder methodology.
