The total synthesis of racemic merrilactone A (a neurotrophic agent) is described, featuring simultaneous and stereospecific creation of the C4 and C5 stereocenters via a notable silyloxyfuran Nazarov cyclization. Full details of the successful synthetic strategy are given, as well as several examples of the interesting reactivity of intermediates that were prepared and studied during the execution
描述了外消旋 merrilactone A(一种神经营养剂)的全合成,其特点是通过显着的甲硅烷氧基呋喃 Nazarov 环化同时和立体定向地创建 C4 和 C5 立体中心。给出了成功合成策略的完整细节,以及在执行全合成过程中制备和研究的中间体的有趣反应性的几个例子。对路易斯酸催化的甲硅烷氧基呋喃 Nazarov 环化进行了详细研究,包括对底物范围和局限性的系统研究。此外,进行的实验表明路易斯酸性硅物质参与了纳扎罗夫环化。
