The hydroquinone lactone core of the floresolides was synthesized through a ring-closing metathesis (RCM) approach. Optimal RCM efficiency was obtained at higher reaction concentration. An unexpected Lewis acid-promoted rearrangement of the hydroquinone and other observations relevant to on-going total synthesis efforts are discussed.
通过闭环复分解(RCM)方法合成了絮状固体的对苯二酚内酯核心。在较高的反应浓度下可获得最佳的RCM效率。讨论了对苯二酚出乎意料的路易斯酸促进的重排以及与正在进行的总合成工作有关的其他观察结果。
