  • Total Synthesis and Biological Evaluation of (+)- and (−)-Bisanthraquinone Antibiotic BE-43472B and Related Compounds
    作者:K. C. Nicolaou、Jochen Becker、Yee Hwee Lim、Alexandre Lemire、Thomas Neubauer、Ana Montero

    respectively) and vancomycin-resistant Enterococcus faecalis (VRE). Described herein is the first total synthesis of both enantiomers of this bisanthraquinone antibiotic, the determination of its absolute configuration, and the biological evaluation of these and related compounds. The developed synthesis relies on a highly efficient cascade sequence involving an intermolecular Diels-Alder reaction between
    双蒽醌抗生素 BE-43472B [(+)-1] 由 Rowley 及其同事从与海鞘 Ecteinascidia turbinata 相关的蓝绿藻中发现的链霉菌菌株中分离,并显示出对临床衍生的甲氧西林分离株的抗菌活性-敏感、耐甲氧西林和耐四环素的金黄色葡萄球菌(分别为 MSSA、MRSA 和 TRSA)和耐万古霉素的粪肠球菌 (VRE)。本文描述的是该双蒽醌抗生素的两种对映异构体的首次全合成、其绝对构型的确定以及这些和相关化合物的生物学评价。开发的合成依赖于高效的级联序列,涉及二烯 (R)-61 和亲二烯体 55 之间的分子间 Diels-Alder 反应,然后是分子内亲核芳族 ipso 取代。后期转化包括显着的光化学 α,β-环氧酮重排 [80 --> (+)-1]。有趣的是,抗生素 BE-43472B 的非天然对映体 [(-)-1] 表现出与天然对映体 [(+)-1] 相当的抗菌特性。

    An‐T‐biotic: The first total synthesis of the T‐shaped bisanthraquinone natural product BE‐43472B was accomplished and its absolute configuration assigned. Key transformations in the pivotal cascade sequence include a Diels–Alder reaction, a hemiketal formation, and a nucleophilic aromatic ipso substitution.

    to inhibit adipogenic differentiation. The natural compound is composed of a γ‐pyrone ring and a side chain and that contains two asymmetric carbons. Although their absolute configuration has been determined, there is no information available on the stereoisomers and their bioactivities. To address this question, we synthesized all four stereoisomers and measured their activities. We also prepared three
    Yoshinone A 源自海藻,可抑制脂肪形成分化。该天然化合物由 γ-吡喃酮环和侧链组成,并含有两个不对称碳。尽管它们的绝对构型已确定,但没有关于立体异构体及其生物活性的信息。为了解决这个问题,我们合成了所有四种立体异构体并测量了它们的活性。我们还制备了另外三种 yoshinone A 衍生物,发现侧链内部的立体构型、γ-吡喃酮环和侧链的体积都在其活性中发挥着重要作用。我们的研究结果应有助于阐明 yoshinone A 的作用机制。
  • Highly Stereoselective Epoxidation of α-Methyl-γ-hydroxy-α,β-unsaturated Esters:  Rationalization and Synthetic Applications
    作者:Irakusne López、Santiago Rodríguez、Javier Izquierdo、Florenci V. González
    DOI:10.1021/jo0709955
    日期:2007.8.1
    The diastereoselectivity of the nucleophilic epoxidation of gamma-hydroxy-alpha, beta-unsaturated esters having a methyl substituent at the alpha- or beta-position was investigated. Epoxidation of the alpha-methyl-substituted enoate was highly stereoselective, giving rise to the syn isomer. This finding was used to perform an enantioselective synthesis of a natural product having a beta-hydroxy-alpha-methylene-gamma-butyrolactone motif. The nucleophilic epoxidation of enoates was found to be irreversible. Models to explain the observed stereoselectivities are proposed.
  • Chemoenzymatic One-Pot Synthesis of γ-Butyrolactones
    作者:Margarete Korpak、Jörg Pietruszka
    DOI:10.1002/adsc.201100110
    日期:2011.6
    AbstractThe synthesis of enantio‐ and diastereomerically pure γ‐butyrolactones is described using a one‐pot, two‐enzyme cascade. Ethyl 2‐methyl‐4‐oxopent‐2‐enoate (2) was reduced selectively first in a 1,4‐reduction using the old yellow enzyme (OYE1) [EC 1.6.99.1] and consecutively in a 1,2‐reduction by an alcohol dehydrogenase [EC 1.1.1.2].
