    名称:
    Asymmetric Total Synthesis of the Stemona Alkaloid (-)-Stenine
    摘要:
    Stenine can be extracted from the roots of the Chinese medicinal plant Stemona tuberosa (Stemonaceae), and its structure and absolute configuration were derived by comparison to the major Stemona alkaloid tuberostemonine. We report the first enantioselective total synthesis of (-)-stenine by a strategy that takes advantage of a diastereoselective end-group-differentiating cyclization in the oxidation of L-tyrosine, The resulting cis-fused indolone is converted to the trans-fused core of stenine upon reduction of a pi-allylpalladium complex, and by stereoselective introduction of four additional stereocenters, a butyrolactone and an azepine ring are attached to this alkaloid building block.

    合成酰基苯三酚支架的合成和多重活性分析。
    摘要:
    这里报道的是新型甲酸介导的脱芳香酰基苯三酚重排,以获得结构多样化的合成酰基苯三酚支架 (SASs)。密度泛函理论 (DFT) 优化的轨道和立体化学分析阐明了这些重排的机制。通过多重活性分析 (MAP) 评估产品,MAP 是一个无偏倚的平台,以单细胞分辨率同时检测多个生物读数,以查找细胞信号转导的标志物,并有助于区分真正的活性和检测干扰。MAP 鉴定了许多抑制 pS6 (Ser235/236) 的 SAS,pS6 是 mTOR 和 ERK 信号通路激活的标志物。这些结果说明了仿生合成和多重活性分析如何通过面向多样性的合成来揭示新型化学型的药理学潜力。

    asymmetric intramolecular oxidopyrylium-alkene [5 + 2]-cycloaddition reaction which resulted in the synthesis of functionalized tricyclic ring systems containing an 8-oxabicyclo[3.2.1]octane core. Intramolecular cycloaddition constructed two new rings, three new stereogenic centers, and provided a tricyclic cycloadduct with high diastereoselectivity and isolated yield. We incorporated an α-chiral center
    我们研究了碱介导的不对称分子内氧化喃-烯烃[5 + 2]-环加成反应,该反应导致合成含有8-氧杂双环[3.2.1]辛烷核心的功能化三环系统。分子内环加成构建了两个新的环,三个新的立体中心,并提供了具有高非对映选择性和分离产率的三环环加合物。我们在底物上加入了一个 α-手性中心和一个烷氧基烯烃系链,并检查了烷基大小和烯烃系链长度对非对映选择性的影响。氧化喃-烯烃环加成反应所需的底物通过几个步骤合成,包括光学活性α-羟基酰胺的烷基化、呋喃加成、所得酮的还原、和 Achmatowicz 反应,然后酰化 lactol 中间体。我们已经提出了通过氧化喃叶立德的 [5 + 2] 环加成反应的立体化学模型。有趣的是,立体中心上的烷氧基取代基和链长决定了环加合物的立体选择性程度。
