  • A Ring Contraction Strategy toward a Diastereoselective Total Synthesis of (+)-Bakkenolide A
    作者:Vânia M. T. Carneiro、Helena M. C. Ferraz、Tiago O. Vieira、Eloisa E. Ishikawa、Luiz F. Silva
    DOI:10.1021/jo100108b
    日期:2010.5.7
    presented from the readily available optically active Wieland−Miescher ketone. This novel synthesis of this sesquiterpene lactone features the following as key stereoselective transformations: (i) the ring contraction reaction of a octalone mediated by thallium(III) nitrate (TTN); (ii) a hydrogenation to create the cis-fused junction; and (iii) the formation of the C7 quaternary center through an enolate intermediate
    从容易获得的旋光的Wieland-Miescher酮中可以发现非对映选择性的途径生成(+)-bakkenolideA。该倍半萜烯内酯的新颖合成具有以下作为关键的立体选择性转化的特征:(i)由硝酸th(III)(TTN)介导的八酮的环收缩反应;(ii)氢化以产生顺式-稠合的连接;(iii)通过烯醇式中间体形成C7四元中心。此外,在这项工作中,分配了从千里光腐殖质分离的三去倍半萜的绝对构型。
  • Structures of Agelasines, Diterpenes Having a 9-Methyladeninium Chromophore Isolated from the Okinawan Marine Sponge<i>Agelas nakamurai</i>Hoshino
    作者:Houming Wu、Hideshi Nakamura、Jun’ichi Kobayashi、Masaki Kobayashi、Yasushi Ohizumi、Yoshimasa Hirata
    DOI:10.1246/bcsj.59.2495
    日期:1986.8
    Novel diterpenes, agelasine-A, -B, -C, -D, -E, and -F were isolated from the Okinawan marine sponge Agelas nakamurai Hoshino and their structures were established to be monocyclic and bicyclic diterpenes having a 9-methyladeninium unit by spectral analyses and chemical transformations.
    从冲绳海海绵 Agelas nakamurai Hoshino 中分离出新的二萜,agelasine-A、-B、-C、-D、-E 和 -F,它们的结构被确定为具有 9-甲基腺嘌呤单元的单环和双环二萜光谱分析和化学转化。
  • Identification of Intermediates in the Biosynthesis of PR Toxin by<i>Penicillium roqueforti</i>
    作者:Ramona Riclea、Jeroen S. Dickschat
    DOI:10.1002/anie.201506128
    日期:2015.10.5
    identified headspace constituent of Penicillium roqueforti. Feeding experiments with 13C‐labeled mevalonolactone isotopomers demonstrated that oxidation at C12 and an isomerization of the C11C12 to a C7C11 double bond must occur independently and not via a C7‐C11‐C12 allyl radical in one step. Feeding with (11,12,13‐13C3)‐7‐epi‐neopetasone resulted in labelling of the PR toxin, thus establishing this compound
    通过Wieland-Miescher酮合成倍半萜类7-表位-新哌替松。该化合物与先前初步确定的罗氏青霉的顶空成分相同。用13种C标记的甲羟戊内酯异位异构体进料的实验表明,C12处的氧化和C11C12到C7C11双键的异构化必须独立发生,而不是一步一步通过C7-C11-C12烯丙基进行。与(11,12,13-喂养13 Ç 3)-7-外延-neopetasone导致PR毒素的标签,从而建立这样的化合物,为新发现的途径中间体。
  • Carbon atom insertion bicycloannulation: total syntheses of ishwarane and ishwarone
    作者:Robert M. Cory、Lester P. J. Burton、Dominic M. T. Chan、Fred R. McLaren、Mary H. Rastall、Richard M. Renneboog
    DOI:10.1139/v84-328
    日期:1984.10.1
    methyllithium at low temperatures. This new bicycloannulation method has been employed in a total synthesis of ishwarane (1), the naturally occurring parent hydrocarbon of the ishwarane class of tetracyclic sesquiterpenes. Although this reaction was not successful with various possible precursors of ishwarone (2), this natural product was prepared in low yield by a two-step version of the carbon atom
    将碳原子插入甲基环己烯,通过卡宾加成到双键和卡宾插入甲基 CH 键,在单一合成步骤中生成双环 [3.2.1.02.7] 辛烷,已通过处理环己烯与四溴化碳和甲基锂在低温下。这种新的双环环化方法已用于 ishwarane (1) 的全合成,这是 ishwarane 类四环倍半萜的天然母烃。尽管该反应对 ishwarone (2) 的各种可能的前体都没有成功,这种天然产物是通过碳原子插入双环环化 (CAIB) 程序的两步形式以低产率制备的,该程序包括将溴仿衍生的二溴卡宾添加到辛酮 (5) 中,然后用甲基锂处理所得的二溴环丙烷 (56)。同样的两步序列也成功地用于 Norishwarane (20) 的第一次合成,该碳氢化合物包含裸...
  • Total synthesis of five natural eremophilane-type sesquiterpenoids
    作者:Zhe Meng、Bo Liu
    DOI:10.1039/c7ob02769a
    日期:——
    The first total syntheses of five natural eremophilane-type sesquiterpenoids were achieved in 4–12 steps via a common synthetic intermediate. The syntheses feature a double Michael addition, Robinson annulation, α-enolization of an unsaturated ketone, and Pd-catalyzed Suzuki coupling reaction to install the side chain. This synthetic strategy could be easily extended to other eremophilane-type sesquiterpenoids
    通过一个普通的合成中间体,在4至12个步骤中完成了5种天然艾草双酚倍半萜类化合物的第一个总合成。合成具有双迈克尔加成反应,罗宾逊环化,不饱和酮的α-烯丙基化和Pd催化的Suzuki偶联反应以安装侧链。这种合成策略可以很容易地扩展到其他具有类似双环骨架的天青石型倍半萜。
