  • Biosynthetically Inspired Divergent Approach to Monoterpene Indole Alkaloids: Total Synthesis of Mersicarpine, Leuconodines B and D, Leuconoxine, Melodinine E, Leuconolam, and Rhazinilam
    作者:Yang Yang、Yu Bai、Siyuan Sun、Mingji Dai
    DOI:10.1021/ol503150c
    日期:2014.12.5
    Inspired by their potential biosynthesis, we have developed divergent total syntheses of seven monoterpene indole alkaloids including mersicarpine, leuconodines B and D, leuconoxine, melodinine E, leuconolam, and rhazinilam, and one unnatural analogue with an unprecedented structural skeleton. The key steps involve a Witkop–Winterfeldt oxidative indole cleavage followed by transannular cyclization
    受到其潜在生物合成的启发,我们开发了七种单萜吲哚生物碱的不同总合成物,其中包括美西卡平,亮二酮B和D,亮氨酸,甜菜碱E,亮氨酸和鼠李糖,以及一种具有空前结构骨架的非天然类似物。关键步骤涉及Witkop–Winterfeldt氧化吲哚裂解,然后进行环环化。然后,通过将跨环环化产物的官能团配对成不同的反应模式,将其转化为相应的结构骨架。
  • Unified enantioselective total syntheses of (−)-scholarisine G, (+)-melodinine E, (−)-leuconoxine and (−)-mersicarpine
    作者:Yao Liu、Honggen Wang

    A unified strategy enabled the enantioselective syntheses of ()-scholarisine G, (+)-melodinine E, ()-leuconoxine and ()-mersicarpine from a common 2-alkylated indole intermediate bearing an all-carbon quaternary stereogenic center. The Smith-modified Madelung indole synthesis was used to couple simple o-toluidine with chiral lactone (+)-8, incorporating the key elements for further cyclizations
    统一的策略能够从带有全碳四元立体构象中心的常见2-烷基化吲哚中间体对映体选择性合成(-)-舒拉瑞辛G,(+)-melodinine E,(-)-leuconoxine和(-)-mersicarpine。Smith修饰的Madelung吲哚合成用于将简单的邻甲苯胺与手性内酯(+)-8偶联,并结合了进一步环化的关键元素。内酯(+)-8是通过钯催化的分子间不对称烯丙基烷基化反应制备的。统一且无保护基团的反应序列允许最多10个步骤高效合成这些生物碱。

    日期:2013.12.26
    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。
  • Total Syntheses of Leuconoxine, Leuconodine B, and Melodinine E by Oxidative Cyclic Aminal Formation and Diastereoselective Ring-Closing Metathesis
    作者:Atsushi Umehara、Hirofumi Ueda、Hidetoshi Tokuyama
    DOI:10.1021/ol500903e
    日期:2014.5.2
    Total syntheses of leuconodine B, melodinine E, and leuconoxine were accomplished via a divergent route. The [5.5.6.6]diazafenestrane skeleton was constructed from an indole-3-acetamide derivative via DMDO oxidation to hydroxylindolenine, TMSOTf/2,6-lutidine mediated cyclic aminal formation, and diastereoseletive ring-closing metathesis of a triene derivative.

    Enantioselective total syntheses of title natural products from a common cyclohexenone derivative (S)-18 were reported. Ozonolysis of (S)-18 afforded a stable diketo ester (R)-17 that was subsequently converted to two skeletally different natural products, i.e., (-)-mersicarpine (8) with a [6.5.6.7] fused tetracyclic ring system and (-)-scholarisine G (9) with a [6.5.6.6.5] fused pentacyclic skeleton
