Various strategies toward the synthesis of the marine natural product (−)-spiroleucettadine are described. In the original strategy, a biomimetic inspired oxidation of a 2-imidazoline scaffold uncovered unexpected reactivity, where benzylic oxidation followed by a Baeyer–Villiger reaction was observed. The second generation approach examined oxidative dearomatization of the phenol ring system first
描述了用于合成海洋天然产物(-)-螺鞘磷脂的各种策略。在最初的策略中,仿生激发了2-咪唑啉骨架的氧化,发现了未预料到的反应性,在该反应中观察到苄基氧化后发生了Baeyer-Villiger反应。第二代方法首先检查了酚环系统的氧化脱芳香化作用,发现了竞争性螺环化过程。通过碳阳离子介导的苄基迁移来锻造支架的努力没有成功。成功合成的亮点包括两个连续的高价碘反应:第一个形成螺环中心,第二个促进乙酸酯基在C-5位置的安装,以便随后引入甲胺侧链。
