  • A Short Total Synthesis of Aureothin and <i>N</i>-Acetylaureothamine
    作者:Mikkel F. Jacobsen、John E. Moses、Robert M. Adlington、Jack E. Baldwin
    DOI:10.1021/ol047594l
    日期:2005.2.1
    The total synthesis of the nitrophenyl pyrones, (+/-)-aureothin and (+/-)-N-acetylaureothamine, starting from known 2-ethyl-6-methoxy-3,5-dimethyl-4H-pyran-4-one are described. The key steps involved in the synthesis are the construction of the tetrahydrofuran motif using a palladium-catalyzed cycloaddition and the ruthenium-catalyzed cross-metathesis reaction of an alkenyl boronic ester.

    从已知的2-乙基-6-甲氧基-3,5-二甲基-4H-吡喃-4-酮开始,硝基苯基吡喃酮,(+/-)-金黄色素和(+/-)-N-乙酰基金胺的总合成被描述。合成中涉及的关键步骤是使用钯催化的环加成反应构建四氢呋喃基序,以及烯基硼酸酯的钌催化的交叉复分解反应。[反应:看文字]
  • Convergent Synthesis of 2-Oxazolone-4-carboxylates Esters by Reaction of Aldehydes with Ambivalent <i>N</i>-Cbz-α-Tosylglycinate Ester
    作者:Masahiro Abe、Baptiste Picard、Michaël De Paolis
    DOI:10.1021/acs.orglett.0c01703
    日期:2020.6.19
    N-Cbz-α-tosylglycinate ester was combined with aldehydes in a redox-neutral sequence leading to 2-oxazolone-4-carboxylates with high functional group tolerance. While the scope of the method was delineated to primary and secondary aliphatic aldehydes as well as aromatics, no racemization occurred with chiral aldehydes such as Garner’s. Hitherto unknown, this process relies on the ambivalent role of
    N -Cbz-α-甲苯磺酰基甘氨酸酯与醛以氧化还原中性顺序结合,产生具有高官能团耐受性的2-恶唑酮-4-羧酸酯。尽管该方法的范围被限定为伯和仲脂族醛以及芳族化合物,但手性醛(如Garner's)未发生外消旋作用。迄今为止未知,该过程依赖于N -Cbz-α-甲苯磺酰基甘氨酸酯作为亲核试剂的矛盾作用。
  • A Concise Route to α′-Methoxy-γ-pyrones and Verticipyrone Based Upon the Desymmetrization of α,α′-Dimethoxy-γ-pyrone
    作者:Michaël De Paolis、Helèna Rosso、Matthias Henrot、Cristina Prandi、Florent d'Herouville、Jacques Maddaluno
    DOI:10.1002/chem.201001780
    日期:——
    Two steps is the rule: A concise synthesis of versatile α′‐methoxy‐γ‐pyrones (see scheme) is described that uses an innovative desymmetrization of α,α′‐dimethoxy‐γ‐pyrone, relying upon conjugate addition of nucleophiles. This new strategy is applied to the preparation of α‐methyl‐ and α‐carboxaldehyde‐α′‐methoxy‐γ‐pyrones and to a short synthesis of verticipyrone.
    规则是两个步骤:描述了一种通用的α'-甲氧基-γ-吡喃酮的简明合成方法(参见方案),该方法利用创新的α,α'-二甲氧基-γ-吡喃酮的去对称性,依赖于亲核试剂的共轭加成。该新策略适用于制备α-甲基和α-甲醛,α'-甲氧基-γ-吡喃酮和维替吡酮的短合成。
  • Absolute Configuration of (+)-Aureothin: A Toxic Metabolite Possessing<i>γ</i>-Pyrone Unit
    作者:Yasuharu Ishibashi、Shigeru Ohba、Shigeru Nishiyama、Shosuke Yamamura
    DOI:10.1246/bcsj.68.3643
    日期:1995.12
    absolute configuration of aureothin (1) has been determined by synthesis of ()-aureonone (4) bearing R-configuration. X-Ray single crystallographic analysis of 21 guaranteed the stereochemistry of the chiral center introduced by Sharpless asymmetric epoxidation, as well as that of isoaureothin (3) which was previously synthesized in a similar pathway. Aureothin (1) itself was also synthesized, although
    aureothin (1) 的绝对构型已通过 (-)-aureonone (4) 轴承 R-构型的合成确定。21 的 X 射线单晶分析保证了由 Sharpless 不对称环氧化引入的手性中心的立体化学,以及之前以类似途径合成的异黄酮 (3) 的立体化学。Aureothin (1) 本身也被合成,尽管 4 在碱性条件下的 Wittig 偶联反应导致手性中心的部分差向异构化。
  • Structural Revision of Griseulin, a Bioactive Pyrone Possessing a Nitrophenyl Unit
    作者:Yasuharu Ishibashi、Shigeru Nishiyama、Shosuke Yamamura
    DOI:10.1246/cl.1994.1747
    日期:1994.9
    Biologically active griseulin isolated from Streptomyces sp. was synthesized, however the spectral data of the synthetic sample did not agree with the reported one. Synthesis of the related sample and detailed reexamination of the spectroscopic properties resulted in the structural revision of griseulin, which should be identical with luteoreticulin.
    从链霉菌中分离出具有生物活性的灰黄霉素,并进行了合成,但合成样品的光谱数据与报告的数据不符。通过对相关样品进行合成并对光谱特性进行详细复查,对灰黄霉素的结构进行了修订,使其与黄曲霉素的结构完全一致。
