Tandem enyne metathesis between 1-alkynes and 1,5-cyclooctadiene or all-cis-1,4-polybutadiene resulted in a direct, one-step ring synthesis of cyclohexadienes by methylene-free metathesis. The use of methylene-free metathesis conditions provided apparent Z-selectivity in the intermolecular enyne metathesis step.
1-炔烃与1,5-环辛二烯或全顺式1,4-聚丁二烯之间的串联烯炔复分解反应通过无亚甲基复分解直接一步合成了环己二烯环。无亚甲基复分解条件的使用在分子间烯炔复分解步骤中提供了明显的Z选择性。
