    摘要:
    (-)-亚奎宁酸具有八种可能的立体异构体,它们既可以天然存在,也可以作为热食品加工的产物出现。在这方面的贡献,我们已经合成了选择性四种异构体,即,外延-quinic酸,粘膜-quinic酸,顺-quinic酸和鲨-quinic酸,开发一个串联LC-MS方法确定所有的立体异构奎尼酸。通过单晶X射线晶体学已明确表征了四种衍生物。通过使用乙酸/浓H 2 SO 4对(-)-奎宁酸进行非选择性异构化,可获得缺少的奎宁酸非对映异构体允许进行色谱分离和奎宁酸的所有非对映异构体分配。我们首次报告,根据其串联质谱碎片质谱图及其洗脱顺序,可以可靠地区分一整套立体异构体。提出了特征性碎片机制的原理。在这项研究中,我们还观察到粘膜-quinic酸,鲨-quinic酸和外延-quinic酸存在于水解危地马拉焙炒咖啡样品焙烧可能的产品。

    The first total synthesis of (+)- and (−)-pericosine A has been achieved, enabling the revision and determination of the absolute configuration of this antitumor natural product as methyl (3S,4S,5S,6S)-6-chloro-3,4,5-trihydroxy-1-cyclohexene-1-carboxylate. Every step of this total synthesis proceeded well with excellent stereoselectivity. Structures of the intermediates in crucial steps were confirmed

    efficient synthesis of antitumor marine natural product (+)-pericosine A was achieved from (−)-quinic acid in 11.7% overall yield, which is 20 times better than our previously reported synthesis. The crucial steps of this synthesis include the regio- and stereoselective bromohydrination of an unstable diene and the ring opening of an epoxide. This synthetic route was applicable to a synthesis of (+)-pericosine

  • Construction of the Bicyclic Core Structure of the Enediyne Antibiotic Esperamicin-A1 in Either Enantiomeric Form from (-)-Quinic Acid
    作者:Gerardo Ulibarri、William Nadler、Troels Skrydstrup、Helene Audrain、Angele Chiaroni、Claude Riche、David S. Grierson
    DOI:10.1021/jo00114a025
    日期:1995.5
    Employed as a common chiral starting material, (-)-quinic acid (7) was converted in a concise manner to both enantiomers of the beta,gamma-unsaturated ketone 12. On the one hand, (+)-12 was obtained by stereospecific borohydride reduction of the conjugated ketone intermediate 9, transketalization, and oxidation of the derived homoallylic alcohol using the Dess-Martin periodinane reagent. Alternatively, dehydration of the tertiary alcohol 13 and oxidation of the free hydroxyl group in 14 furnished (-)-12 in good overall yield. Reaction of (+)-12 with dichlorocerium TMS acetylide was followed by Pd(0)-assisted construction of the acyclic enediyne 21. Cyclization of this intermediate on treatment with KHMDS proved efficient, providing the esperamicin intermediate (-)-22 in 60% isolated yield. In an identical fashion -)-12 was converted to the enantiomeric bicyclic enediyne (+)-22. Subsequent liberation of the diol system, and selective oxidation of the allylic alcohol in 25 gave ketone 26. Reaction of this intermediate with Ph(2)S=NH monohydrate gave aziridine 27 which was readily converted to its carbamate derivative 28 in preparation for aziridine ring opening.
