  • A Family of New 1,2,4-Trioxanes by Photooxygenation of Allylic Alcohols in Sensitizer-Doped Polymers and Secondary Reactions
    作者:Axel G. Griesbeck、Anna Bartoschek、Tamer T. El-Idreesy、Lars-Oliver Höinck、Johann Lex、Claus Miara、Jörg M. Neudörfl

    Type II photooxygenation (singlet oxygen) is described as a synthetically useful way for the preparation of allylic hydro­peroxides and endoperoxides using sensitizer-adsorbed or covalently sensitizer-doped polymeric (macro- or nanosized) containers. Facilitated product separation and purification as well as increased reactivity are advantages of these techniques in comparison with solution-phase photochemistry. The products generated by Type II photooxygenation have been used for the syntheses of numerous polycyclic peroxides with a common 1,2,4-trioxane core as exhibited in the natural antimalarial artemisinin.
    II型光氧化(单重态氧)被描述为一种合成上有用的方法,用于通过感光剂吸附或共价掺杂感光剂的聚合物(宏观或纳米尺寸)容器合成烯丙基过氧化氢和端过氧化物。这些技术相比于溶液相光化学的优点在于可以促进产物的分离和纯化,并提高反应活性。通过II型光氧化生成的产物已被用于合成众多具有共同1,2,4-三氧烯核心的多环过氧化物,这在天然抗疟药青蒿素中得到了体现。
  • Ru(II)–Pheox-Catalyzed Asymmetric Intramolecular Cyclopropanation of Electron-Deficient Olefins
    作者:Yoko Nakagawa、Soda Chanthamath、Kazutaka Shibatomi、Seiji Iwasa

    日期:2015.6.5
    The first highly enantioselective intramolecular cyclopropanation of electron-deficient olefins, in the presence of Ru(II)–-Pheox catalyst, is reported. The corresponding cyclopropane-fused γ-lactones were obtained in high yields (up to 99%) with excellent enantioselectivities (ee up to 99%). Moreover, this method enables efficient access to enantioenriched dicarbonyl cyclopropane derivatives, which
    据报道,在Ru(II)-Pheox催化剂存在下,电子缺陷性烯烃的首次高对映选择性分子内环丙烷化反应。以高产率(高达99%)和优异的对映选择性(ee高达99%)获得了相应的环丙烷稠合的γ-内酯。而且,该方法使得能够有效地获得对映体富集的二羰基环丙烷衍生物,其是合成各种生物活性化合物的重要中间体。
  • Total Synthesis of (−)-Nodulisporic Acid D
    作者:Yike Zou、Jason E. Melvin、Stephen S. Gonzales、Matthew J. Spafford、Amos B. Smith

    日期:2015.6.10
    A convergent total synthesis of the architecturally complex indole diterpenoid (-)-nodulisporic acid D has been achieved. Key synthetic transformations include vicinal difunctionalization of an advanced α,β-unsaturated aldehyde to form the E,F-trans-fused 5,6-ring system of the eastern hemisphere and a cascade cross-coupling/indolization protocol leading to the CDE multisubstituted indole core.
    结构复杂的吲哚二萜 (-)-nodulisporic 酸 D 的收敛全合成已经实现。关键的合成转化包括先进的 α,β-不饱和醛的邻位双官能化以形成东半球的 E,F-反式融合 5,6-环系统和导致 CDE 多取代吲哚的级联交叉偶联/吲哚化方案核。
  • Total Synthesis of (±)Variotin and Its Analogs
    作者:Akihiko Ishida、Teruaki Mukaiyama
    DOI:10.1246/bcsj.51.2077
    日期:1978.7
    1-Sorboyl-2-pyrrolidone was prepared from sorbic acid and 2-ethoxy-1-pyrroline using 1-methyl-2-chloropyridinium iodide as a coupling reagent. Variotin and its analogs were similarly synthesized from lactim ethers and (2E,4E,6E)-8-hydroxy-2,4,6-dodecatrienoic acids without protecting the hydroxyl group at C-8. (2E,4E,6E)-8-Hydroxy-6-methyl-2,4,6-dodecatrienal, a precursor of trienoic acid, was synthesized by the elimination of methanol from (2E,6E)-8-acetoxy-5-methoxy-6-methyl-2,6-dodecadienal prepared from the reaction of 1-trimethylsiloxy-1,3-butadiene with (2E)-4-acetoxy-2-methyl-2-octenal dimethyl acetal.
    使用 1-甲基-2-氯吡啶鎓碘化物作为偶联试剂,从山梨酸和 2-乙氧基-1-吡咯啉制备出 1-山梨醇基-2-吡咯烷酮。变异素及其类似物同样也是由内脂醚和 (2E,4E,6E)-8-羟基-2,4,6-十二碳三烯酸合成的,但没有保护 C-8 处的羟基。(2E,4E,6E)-8-羟基-6-甲基-2,4,6-十二碳三烯醛是由 1-三甲基硅氧基-1,3-丁二烯与(2E)-4-乙酰氧基-2-甲基-2-辛烯醛二甲基缩醛反应制备的(2E,6E)-8-乙酰氧基-5-甲氧基-6-甲基-2,6-十二碳二烯醛通过消除甲醇合成的,而(2E,6E)-8-羟基-6-甲基-2,4,6-十二碳三烯醛是三烯酸的前体。

    size of the ester alkoxy group. The same products were obtained from the NBS treatment of methyl angelate (2b). This NBS-bromination appears to be thermodynamically controlled, since both angelic and tiglic acid as well as their methyl esters were brought into equilibrium (1 ⇆ 2 = > 9:1) with catalytic amounts of NBS.
    tigtig甲酯(1b)的Wohl - Ziegler溴化(N-溴代琥珀酰亚胺= NBS)得到了γ-溴代甲基丙烯酸酯(3b)和β'-溴代甲基丙烯酸酯(5b)的2:1混合物。γ-溴化与β'-溴化的比率不受溶剂,催化剂或酯烷氧基基团尺寸变化的影响。从NBS处理的当归酸甲酯(2b)获得了相同的产品。这种NBS溴化似乎是热力学控制的,因为当量的NBS催化使天使酸和tiglic酸及其甲基酯达到平衡(1⇆2 => 9:1)时。
