  • The Amino Thiourea-Catalyzed Asymmetric Nucleophilic Reactions
    作者:Yoshiji Takemoto、Hideto Miyabe
    DOI:10.2533/chimia.2007.269
    日期:——

    Bifunctional amino thiourea-catalyzed asymmetric additions of several nucleophiles into electron-deficient unsaturated compounds such as nitroolefins, ?,?-unsaturated imides, imines, and azodicarboxylates are described. We discovered that bifunctional thioureas bearing a tertiary amino group significantly accelerated several nucleophilic addition reactions of active methylene compounds to electron-deficient double bonds. In these reactions, a strong hydrogen-bonding ability of the thiourea moiety as well as an appropriate Brønsted basicity of the tertiary amine is crucial for high enantioselectivity. This dual activation of both nucleophiles and electrophiles by the bifunctional thiourea expanded the applicability of the thiourea-catalyzed enantioselective reaction. In addition, these organocatalyzed asymmetric reactions were successfully applied to the concise asymmetric synthesis of natural products and medicinal candidates such as epibatidine, baclofen, and CP-99,994.

    双功能氨基硫脲催化的不对称加成反应将几种亲核试剂加入到电子不足的不饱和化合物中,如硝基烯烃、α,β-不饱和亚酰胺、亚胺和叠氮二羧酸酯。我们发现,含有三级胺基的双功能硫脲显著加速了活性亚甲基化合物与电子不足双键的几种亲核加成反应。在这些反应中,硫脲基团的强氢键能力以及三级胺的适当Brønsted碱性对高对映选择性至关重要。双功能硫脲对亲核试剂和电子亲电试剂的双重活化扩展了硫脲催化的不对称反应的适用范围。此外,这些有机催化的不对称反应成功应用于天然产物和药用候选化合物的简洁不对称合成,如蛙毒碱、氯硝西泮和CP-99,994。
  • Total synthesis of (±) epibatidine
    作者:Rui Xu、Guohua Chu、Donglu Bai

    日期:1996.2
    An efficient total synthesis of the non-opiate antinociceptive alkaloid epibatidine is described. Distinctly different from the previously published approaches it features the novel synthesis of the 7-azabicyclo[2.2.1]heptane ring system by contraction of the tropinone skeleton via Favorskii rearrangement.

    (1), isolated from the skin of the Ecuadoran poison frog was synthesized in racemic form starting from tropinone. Distinctly different from the previously published approaches, this synthesis features the novel synthesis of the 7-azabicyclo[2.2.1]heptane ring system by contraction of the tropinone skeleton viaFavorskii rearrangement. Five analogues of 1 were also prepared, and their analgesic activities

    2'-chloropyridine ring bridged to the 7-azabicyclo[2.2.1]heptane ring via a methylene group, were synthesized, where the key step was an intramolecular reductive palladium-catalyzed Heck-type coupling. Even though the conformationally restricted epibatidine analogues, 3- 7, and the benzo analogue 8a possess nAChR pharmacophore features thought to be needed for alpha(4)beta(2) binding, they all showed low affinity
    通过以下步骤合成具有与7-氮杂双环[2.2.1]庚烷环的2,3位稠合的吡啶环的依巴替丁类似物3-5,和具有与5,6位稠合的苯环的吡啶类似物8a。涉及用1 H-吡咯-1-羧酸叔丁酯捕集2,3-吡啶,3,4-吡啶和苯炔的关键步骤。合成了两个表巴替丁类似物6和7,它们具有通过亚甲基桥接到7-氮杂双环[2.2.1]庚烷环上的2'-氯吡啶环,其中的关键步骤是分子内还原钯催化的Heck-类型耦合。即使构象受限的依巴替丁类似物3- 7和苯并类似物8a具有被认为是alpha(4)beta(2)结合所必需的nAChR药效团特征,但相对于epibatidine,它们都显示出对nAChR的低亲和力。这些研究提供了有关nAChRs药效团的新信息,并表明氮孤对的方向性和空间因素可能很重要。有趣的是,作为研究桥接类似物6和7的标准化合物而制备的N-甲基表巴替丁是一种有效的nAChR混合激动剂拮抗剂。
