  • Pentadienyl Type Lithium and Potassium Species: The Regioselectivity of their Reactions with Electrophiles
    作者:Manfred Schlosser、Armin Zellner、Frédéric Leroux
    DOI:10.1055/s-2001-17521
    日期:——
    Seven structurally distinct pentadienyl type lithium and potassium compounds were screened against a variety of electrophiles in order to assess the regioselectivity of the trapping reactions. Organoborates and analogs thereof (fluorodimethoxyborane) proved to be perfectly regioreliable attacking only unsubstituted terminal positions and thus providing, after oxidation, exclusively primary allylic alcohols. 2,4-Pentadienyllithiums or -potassiums, that carry a methyl group at the 1- or 3-position, exhibit the same extreme regioselectivity towards halotrialkylsilanes or carbon dioxide. Although the unsubstituted parent compounds combine with such electrophiles still preferentially at the terminal position, considerable proportions of branched products are concomitantly formed as well (1/3-attack ratios ranging from 2:1 to > 20:1). Hydroxyalkylating and alkylating reagents such as formaldehyde, oxirane or butyl iodide invariably afford regioisomeric mixtures generally varying in composition between 3:1 and 1:3. The condensation reaction with halotrialkylsilanes appears to follow a concerted (SN2-like) rather than an addition/elimination (ate complex-mediated) mechanism.
    进行了七种结构不同的戊二烯基型锂和钾化合物的筛选,以评估它们与各种亲电试剂反应的区域选择性。有机硼酸盐及其类似物(氟二甲氧基硼烷)显示了非常可靠的区域选择性,仅攻击未取代的末端位置,因此氧化后只得到完全的一级烯丙基醇。带有甲基的2,4-戊二烯基锂或钾在1-或3-位置上,对卤代三烷基硅烷或二氧化碳显示出相同的极端区域选择性。尽管未取代的母体化合物仍优先在末端位置与这些亲电试剂反应,但同时也会生成相当比例的支链产物(1/3-攻击比例从2:1到超过20:1)。羟烷基化和烷基化试剂,如甲醛、环氧乙烷或丁基碘,总是得到区域异构体的混合物,其组成通常在3:1和1:3之间变化。与卤代三烷基硅烷的缩合反应似乎遵循协同(类似SN2)而非加成/消除(通过ate复合体介导)的机制。
  • Synthesis and Cannabinoid Receptor Activity of Ketoalkenes from<i>Echinacea pallida</i>and Nonnatural Analogues
    作者:Michael Egger、Patrina Pellett、Kathrin Nickl、Sarah Geiger、Stephanie Graetz、Roland Seifert、Jörg Heilmann、Burkhard König

    ketoalkenes using palladium-catalyzed cross-coupling reactions and the pharmaceutical results at the human cannabinoid receptors. The synthetic route developed provides overall good yields for the ketoalkenes and is applicable to other natural products with similar 1,4-diene motifs. No significant activity was observed at either receptor, indicating that the ketoalkenes from E. pallida are not responsible
    尽管紫锥花产品的普及和广泛使用,其功效仍不清楚和有争议。在从紫锥菊中分离出的各种化合物中,仅在淡紫色锥花(E. pallida)中发现的酮烯和酮烯酮是提取物的主要成分。与紫癜链烷酰胺相反,这些化合物尚未合成和研究过免疫刺激作用。我们提出了使用钯催化的交叉偶联反应和对人类大麻素受体的药物合成结果,对酮烯烃的实用和有用的合成方法。所开发的合成路线为酮烯提供了总体良好的收率,并且适用于具有相似的1,4-二烯基序的其他天然产物。在任一受体上均未观察到明显的活性,表明来自E的酮烯。帕利达(Pallida)对通过大麻素系统介导的免疫调节作用不负责任。但是,新合成的非天然类似物在两种大麻素受体上均表现出微摩尔效价。
  • Z-Stereoselective semi-reduction of alkynes: modification of the Boland protocol
    作者:Yasser M.A. Mohamed、Trond Vidar Hansen
    DOI:10.1016/j.tet.2013.03.038
    日期:2013.5
    Highly Z-selective semi-reduction of alkynes has been achieved by adding TMSCl to a mixture of Zn(Cu/Ag), water, and methanol. The conjugated Z-alkenes have been prepared in high yields at ambient temperature. The formation of isomeric E-alkenes and over-reduction to alkanes were suppressed in our modified Boland reduction protocol. The methodology was extended to the preparation of Z-substituted stilbenes
    通过将TMCSC1添加到Zn(Cu / Ag),水和甲醇的混合物中,可以实现炔烃的高度Z-选择性的半还原。在环境温度下已经以高收率制备了共轭Z-烯烃。在我们改进的Boland还原方案中,抑制了异构体E-烯烃的形成和烷烃的过度还原。该方法扩展到了Z-取代的对苯二甲酸酯的制备。

    The synthesis of the novel silyl acetal-containing triene 1 is described. Triene 1 underwent regiospecific and highly stereoselective intramolecular Diels-Alder reaction to give bicycle 5. Acidic methanolysis of 5 gave hydroxylactone 2, whose structure was established by X-ray crystallography.

  • Pericyclic reactions in nature: Evidence for a spontaneous [1.7]-hydrogen shift and an 8πe electrocyclic ring closure in the biosynthesis of olefinic hydrocarbons from marine brown algae (phaeophyceae).
    作者:Georg Pohnert、Wilhelm Boland
    DOI:10.1016/s0040-4020(01)81756-7
    日期:1994.8
    The stereochemistry of the algal C11H16 hydrocarbon giffordene 3 results from a spontaneous [1.7]-sigmatropic hydrogen shift of the thermolabile (1,3Z,5Z,8Z)-undecatetraene 8. An 8πe electrocyclisation of (1,3Z,5Z,-7E)-nonatetraene 9 is substantiated for the biosynthesis of 7-methylcyclooctatriene 5, a product of the Mediterranean brown alga Cutleria multifida. Low temperature syntheses (−30 °C) of
