摘要:
An enyne metathesis/ring closing metathesis (EM/RCM) sequence was used to synthesise acyloxy-semicyclic dienes from an enyne substrate and various vinyl esters. This allowed convenient access to acyloxy-semicyclic dienes not accessible by cross metathesis alone due to the low reactivity of Fischer carbenes with the termini of 1,3-dienes. This new approach also provides an alternative method for the synthesis of 1-acyloxy-1,3-dienes which are useful reactants for Diels-Alder cycloadditions.
