toward the synthesis of the macrocyclic thiolactone core of griseoviridin have been studied. Intramolecular palladium-catalyzed thiol coupling and esterification (carboxylate activation) have led to the formation of unexpected rearranged products. An intermolecular palladium-catalyzed thiol/vinyl iodide coupling followed by an esterification (alcohol activation) ultimately led to the nine-membered
已经研究了三种合成灰黄绿异丁烯的大环硫代内酯核心的方法。分子内钯催化的硫醇偶联和酯化(羧酸酯活化)导致形成意想不到的重排产物。分子间钯催化的硫醇/碘化乙烯偶联,然后进行酯化(酒精活化),最终导致灰黄霉素的九元核心。
