  • Total Synthesis of Lennoxamine and Chilenine via Ring-Expansion of Iso- indoloisoquinoline to Isoindolobenz- azepine
    作者:Tatsuo Nagasaka、Yuji Koseki、Shinya Katsura、Shuichi Kusano、Harumi Sakata、Hiroto Sato、Yoshinori Monzene
    DOI:10.3987/com-02-s50

    Convenient synthesis of the benzazepine alkaloids, lennoxamine (1) and chilenine (2), is described. The key steps are conversion of methylenelactam (5) to an N-tertiary acyliminium ion precursor (16) and a novel expansionof the six-membered ring of 4 to a benzazepine ring system (3b), which could be transformed into lennoxamine (1) and chilenine (2).
    描述了苯并西平生物碱、lennoxamine (1) 和 chilenine (2) 的方便合成。关键步骤是将亚甲基内酰胺 (5) 转化为 N-叔酰基亚胺离子前体 (16),并将 4 的六元环扩展为苯并氮杂环系统 (3b),后者可以转化为列诺沙明 (1)和辣椒碱 (2)。
  • An efficient method for the synthesis of enol ethers and enecarbamates. Total syntheses of isoindolobenzazepine alkaloids, lennoxamine and chilenine
    作者:Haruhiko Fuwa、Makoto Sasaki
    DOI:10.1039/b706087d
    日期:——
    An efficient method for the synthesis of enol ethers and enecarbamates has been developed based on catalytic hydrosilane reduction of alpha-phosphonoxy enol ethers and alpha-phosphonoxy enecarbamates. This method has been applied to the total syntheses of two isoindolobenzazepine alkaloids, lennoxamine and chilenine.
    基于α-膦酰氧基烯醇醚和α-膦酰氧基烯甲酸酯的催化氢化硅烷还原,已经开发了一种用于合成烯醇醚和烯甲酸酯的有效方法。该方法已应用于两种异吲哚并苯并ze庚碱生物碱伦诺沙明和卡列宁的合成。
  • Regio- and Stereoselective Electrophilic Cyclization Approach for the Protecting-Group-Free Synthesis of Alkaloids Lennoxamine, Chilenine, Fumaridine, 8-Oxypseudoplamatine, and 2-<i>O</i>-(Methyloxy)fagaronine
    作者:Tuanli Yao、Zhen Guo、Xiujuan Liang、Lihan Qi
    DOI:10.1021/acs.joc.8b02154
    日期:2018.11.2
    protecting-group-free synthesis of alkaloids lennoxamine, chilenine, fumaridine, 8-oxypseudoplamatine, and 2-O-(methyloxy)fagaronine is reported. The core isoindolin-1-one and isoquinolin-1-one structures were built by a silver-catalyzed regio- and stereoselective cyclization of methyl 2-alkynylbenzimidates. The regioselectivity of cyclization was achieved by utilizing the intrinsic functionality of alkaloids.

    reported. This synthesis represents the most efficient and shortest route to date, featuring three catalytic processes: CuI‐catalyzed redox‐A3 reaction, Pdcatalyzed reductive carbocyclization, and PtO2‐catalyzed hydrogenation. Importantly, this new strategy to the tetracyclic framework has also been applied to the collective concise syntheses of >30 natural protoberberines (without 13‐methyl group) and
    报告了一种简洁,催化和通用的策略,该策略允许在四个步骤中为每个分子高效地合成22种天然13-甲基原小ber碱。该合成代表了迄今为止最有效,最短的路线,具有三个催化过程:CuI催化的氧化还原A 3反应,Pd催化的还原碳环化和PtO 2催化的氢化。重要的是,这种针对四环框架的新策略也已应用于30多种天然原小ber碱(无13-甲基)和5种金刚烷生物碱的集体简明合成中。

    日期:2019.3.1
    Pd(OAc)2-catalyzed intramolecular dehydrogenative cross-coupling reaction between tertiary enamides, which were derived from the condensation of 2-arylethylamines and methyl o-acetylbenzoate, and arenes enabled synthesis of 7,8-dihydro-5H-benzo[4,5]azepino[2,1-a]isoindol-5-one derivatives under mild conditions. The synthetic method was applied in the total synthesis of aporhoeadane alkaloids palmanine
