entire family of prostaglandins according to Corey′s route. Furthermore, the reactivity and enantioselectivity of B‐V oxidation of racemic bicyclic cyclobutanones were evaluated and 90–99 % ee was obtained, representing one of the most efficient routes to chiral lactones. This study further facilitates the synthesis of prostaglandins and chiral lactone‐containing natural products to promote drug discovery
开发了一种新的协议,该协议使用立体控制的有机催化Baeyer-Villiger(B-V)氧化来构建前列腺素的关键双环内酯。用过氧化氢水溶液对外消旋环丁酮衍生物进行关键的B-V氧化,可以早期构建对映体过量(最高95%)的双环内酯骨架。产生的双环内酯完全充满两个所需的立体中心,并能够根据Corey的路线合成整个前列腺素家族。此外,还评估了外消旋双环环丁酮的B-V氧化反应的反应性和对映选择性,且ee值为90–99%获得了代表手性内酯的最有效途径之一。这项研究进一步促进了前列腺素和手性内酯天然产物的合成,从而促进了药物的发现。
