Members of the coleophomone family of natural products all possess several intriguing and challenging architectural features, as well as exhibit unusual biological activity. They, therefore, constitute attractive targets for synthesis. In this Article, we describe the total synthesis of coleophomones B (2), C (3), and D (4). The highly strained and congested 11-membered macrocycle of coleophomones
天然产物木香酚家族的成员都拥有几个有趣和具有挑战性的建筑特征,并表现出不寻常的生物活性。因此,它们构成了有吸引力的合成目标。在本文中,我们描述了鞘氨醇 B (2)、C (3) 和 D (4) 的全合成。使用令人印象深刻的烯烃复分解反应构建了高度紧张和拥堵的 11 元大环鞘氨醇 B (2) 和 C (3)。此外,大环内 Delta(16,17) 的两种必要几何异构体都可以从一个共同的前体中获得,从而促进了发散,从而使鞘磷脂 B (2)/C (3) 的合成具有异常高的效率.
