  • Asymmetric Total Synthesis of (−)-Leuconoxine via Chiral Phosphoric Acid Catalyzed Desymmetrization of a Prochiral Diester
    作者:Kazuhiro Higuchi、Shin Suzuki、Reeko Ueda、Norifumi Oshima、Emiko Kobayashi、Masanori Tayu、Tomomi Kawasaki
    DOI:10.1021/ol5033865
    日期:2015.1.2
    The asymmetric total synthesis of ()-leuconoxine has been achieved. The desymmetrization of a prochiral diester using a chiral phosphoric acid catalyst produced a highly enantioenriched lactam with excellent yield. The ring construction featuring an intramolecular N-acyliminium cyclization and the one-step pyrrolidone formation using Bestmann’s ylide was successfully accomplished.
    (-)-leuconoxine的不对称全合成已经实现。使用手性磷酸催化剂对前手性二酯进行脱对称化可得到高对映体富集的内酰胺,收率极好。成功实现了分子内N-酰基环化和使用Bestmann ylide一步形成吡咯烷酮的环结构。
  • A Photoinduced Cyclization Cascade-Total Synthesis of (−)-Leuconoxine
    作者:Magnus Pfaffenbach、Tanja Gaich
    DOI:10.1002/chem.201500656
    日期:2015.4.20
    enantioselective total synthesis of the monoterpenoid indole alkaloid ()‐leuconoxine was accomplished. The key step comprises a novel photoinduced domino macrocyclization/transannular cyclization involving the Witkop cyclization, for which additional mechanistic evidence is provided. This process furnishes a diaza[5.5.6.6]fenestrane skeleton, which is a hitherto unprecedented structure element.
    完成了单萜类吲哚生物碱(-)-leuconoxine的无保护基团和对映选择性总合成。关键步骤包括涉及Witkop环化的新型光诱导的多米诺骨化大环化/环过环化,为此提供了更多的机理证据。该过程提供了二氮杂[5.5.6.6] fenestrane骨架,这是迄今为止前所未有的结构元素。
  • 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
    DOI:10.1039/c8cc09949a
    日期:——
    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。
  • Total Synthesis of Leuconoxine, Melodinine E, and Mersicarpine through a Radical Translocation–Cyclization Cascade
    作者:Ryan Kim、Andrew J. Ferreira、Christopher M. Beaudry
    DOI:10.1002/anie.201907455
    日期:2019.9.2
    The Aspidosperma alkaloids leuconoxine, melodinine E, and mersicarpine were synthesized. The approach features a key cascade radical reaction. A 1,5-hydrogen atom transfer is followed by spontaneous 5-exo-trig cyclization to construct the central indoline architecture. Late-stage differentiation of the radical cyclization product by chemoselective oxidation allows production of either the leuconoxine/melodinine E
    合成了天冬子孢子碱的生物碱亮氨酸,甜菜碱E和美卡西平。该方法具有关键的级联自由基反应。1,5-氢原子转移后,自发地进行5-exo-trig环化,以构建中央二氢吲哚结构。通过化学选择性氧化对自由基环化产物进行后期区分,可以产生亮氨酸氧代/ melodinine E或马西卡平结构。
