peroxidation of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are consumed daily for the prevention of cardiovascular and neurological pathologies. To facilitate in depth studies concerning the effects of these oxidized isoprostanoids on human health, labeled derivatives are necessary. In this paper, we have accomplished the first total synthesis of labeled A-type cyclopentenone
通过体内二十碳五烯酸(EPA)和二十二碳六烯酸(DHA)的自由基过氧化作用,体内大量形成A型环戊烯酮异前列腺素,它们是日常食用,可预防心血管和神经系统疾病。为了促进有关这些氧化的异前列腺素对人体健康的影响的深入研究,标记的衍生物是必要的。在本文中,我们完成了标记的A型环戊烯酮异前列腺素的首次全合成,即17,18- [D 2 ] -15-A 3t -IsoP和19,20- [D 2 ] -17-A 4t-NeuroP。两条对映选择性路线是高度收敛的,它们来自一个常见的中间体,可通过Julia-Kocienski反应轻松获得,并且具有炔烃部分的半氢化作用,用于安装标记的下侧链。
