    在高活性抗生素20-脱氧-Elansolid B1的仿生全合成中利用对甲醌醌甲壳素
    摘要:
    聚酮化合物20-脱氧elansolid B1是通过收敛策略制备的,该策略依赖于假定的仿生分子内Diels-Alder环加成反应(IMDA),通过乙烯基对苯醌甲基化物中间体提供关键的四氢茚满单元。(Z,E,Z)配置的三烯单元是由Pd催化的Suzuki-Miyaura和Stille交叉偶联反应构建的,没有任何烯烃双键的异构化。在碱性条件下对甲基苯醌中间体的形成以及随后用水将该中间体的迈克尔加成反应以高的面部选择性进行,从而终止了该总合成。值得注意的是,新的elansolid衍生物2 c对枯草芽孢杆菌和金黄色葡萄球菌(包括MRSA)具有很好的抑制作用,与迄今为止报道的最好的伊兰固素衍生物相似。因此,C 20的羟基对于抗菌活性不是必需的。

    Dinuclear Asymmetric Zn Aldol Additions:  Formal Asymmetric Synthesis of Fostriecin
    摘要:
    Direct asymmetric aldol reactions constitute a powerful methodology for the efficient synthesis of complex natural products. Herein we report the first application of our recently reported dinuclear Zn-catalyzed direct aldol addition of alkynyl ketones to aldehydes in a short and efficient formal asymmetric synthesis of fostriecin, a potent cyctotoxic natural product. This work highlights not only the power of the aldol methodology but also the utility of the akynyl silane aldol adducts, as it is subsequently utilized in a vinyl silane cross-coupling reaction which affords the target molecule in 14 steps for the longest linear sequence in 8.5% overall yield.

  • Modular Approaches to Lankacidin Antibiotics

    Lankacidins are a class of polyketide natural products isolated from Streptomyces spp. that show promising antimicrobial activity. Owing to their complex molecular architectures and chemical instability, structural assignment and derivatization of lankacidins is challenging. Herein we describe three fully synthetic approaches to lankacidins that enable access to new structural variability within the
    兰卡西丁是从链霉菌属中分离出来的一类聚酮化合物天然产物。显示出有希望的抗菌活性。由于其复杂的分子结构和化学不稳定性,lankacidins 的结构分配和衍生化具有挑战性。在此,我们描述了三种完全合成的 lankacidins 方法,这些方法能够获得该类中新的结构变异性。我们使用这些路线系统地生成环状和非环状 lankacidins 的立体化学衍生物。此外,我们获得了在 C4 位带有甲基的新系列 lankacidin,这是一种旨在提高化学稳定性的修饰。在这项工作的过程中,我们发现 lankacidin 类的两种天然产物的报告结构是不正确的,我们确定了 2 的正确结构,18-seco-lankacidinol B 和iso-lankacidinol。我们还评估了几种 iso- 和 seco-lankacidin 抑制细菌生长和体外翻译的能力。这项工作有助于深入了解此类抗生素的丰富化学复杂性,并为进一步结构衍生化提供了途径。

    developed a route to stereochemically diverse variants of 2,18‐seco‐lankacidinol B and found that the stereochemical assignment at C4 requires revision. This has interesting implications for the biosynthesis of natural products of the lankacidin class, all of which possessed uniform stereochemistry prior to this finding. We have evaluated 2,18‐seco‐lankacidinol B and three stereochemical derivatives against
    兰卡西丁是一组聚酮化合物天然产物,具有对抗多种革兰氏阳性菌菌株的活性。我们开发了一条获得 2,18- seco -lankacidinol B 立体化学多样化变体的路线,并发现 C4 的立体化学分配需要修改。这对于兰卡西丁类天然产物的生物合成具有有趣的意义,在这一发现之前,所有这些天然产物都具有统一的立体化学。我们评估了 2,18- seco -lankacidinol B 和三种立体化学衍生物对一组致病性革兰氏阳性和革兰氏阴性细菌的作用。

    A synthesis of the unsaturated side chain of callyspongiolide has been accomplished from two chiral building blocks prepared by catalytic asymmetric procedures applied on simple starting materials. The synthesis of the chiral benzylic alcohol was based on an enantioselective aldol reaction of a substituted benzaldehyde catalyzed by a chiral amine, whereas the chiral homoallyl alcohol was prepared by

    Combinatorial synthesis of a 1,5-polyol system corresponding to the C1-C14 unit of amphidinol 3 (AM3) and its diastereomers was achieved via chemoselective cross metathesis as the key step. Comparison of (13)C NMR data of the synthetic specimens with that of AM3 led to a controversy regarding the originally proposed structure. From GC-MS analysis of the degradation product, the absolute configuration

  • Synthesis of 2- and 2,3-Substituted Pyrazolo[1,5-<i>a</i>]pyridines: Scope and Mechanistic Considerations of a Domino Direct Alkynylation and Cyclization of <i>N</i>-Iminopyridinium Ylides Using Alkenyl Bromides, Alkenyl Iodides, and Alkynes
    作者:James J. Mousseau、James A. Bull、Carolyn L. Ladd、Angélique Fortier、Daniela Sustac Roman、André B. Charette
    DOI:10.1021/jo201303x
    日期:2011.10.21
    Direct functionalization and tandem processes have both received considerable recent interest due to their cost and time efficiency. Herein we report the synthesis of difficult to obtain 2-substituted pyrazolo[1,5-a]pyridines through a tandem palladium-catalyzed/silver-mediated elimination/direct functionalization/cyclization reaction involving N-benzoyliminopyridinium ylides. As such, these biologically important molecules are prepared in an efficient, high-yielding manner, only requiring a two-step sequence from pyridine. Aryl-substituted alkenyl bromides and iodides are effective ylide coupling partners. Mechanistic studies led to the use of terminal alkynes, which extended the scope of the reaction to include alkyl substitution on the unsaturated reactive site. The optimization, scope, and mechanistic considerations of the process are discussed.
