A unified strategy allowing enantioselective total syntheses of (-)-mersicarpine, (-)-scholarisine G, (+)-melodinine E, (-)-leuconoxine, and (-)-leuconolam from a common cyclohexenone derivative was reported. The Suzuki-Miyaura reaction was used to couple two simple fragments incorporating the key elements for total synthesis, and unprecedented oxidation/reduction/cyclization processes were developed
报道了一种统一的策略,允许从常见的环己烯酮衍生物对映选择性全合成 (-)-mersicarpine、(-)-scholarisine G、(+)-melodinine E、(-)-leuconoxine 和 (-)-leuconolam。Suzuki-Miyaura 反应用于结合两个包含全合成关键元素的简单片段,并开发了前所未有的氧化/还原/环化过程,将取代的环己烯酮转化为花红素或亮氨酸骨架。在反向仿生合成方式中,(+)-melodinine E 在酸性条件下转化为 (-)-leuconolam。
