    摘要:
    萘醌是多种药物和天然产物的核心。因此,1,4-萘醌与有机结构单元的结合将为具有生物学意义的支架提供一种简便的策略。在这方面,我们在此报告了 Ru(II) 催化的 1,4-萘醌与苯甲酸的 [4 + 2] 环化反应,得到了各种萘醌内酯。此外,还说明了在 Ru(II) 催化下使用苯乙酮对萘醌进行酮定向芳基化。这些前体的原料可用性允许在相当温和的条件下以良好到极好的收率访问大型萘醌衍生物库。通过进行克级合成和进一步功能化,证明了这些协议的实用性。还,

    We describe here a novel synthesis of benzo[b]naphtho[2,3-d]furan-6,11-diones based on the heteroannulation of 2-(2-bromophenyl)-3-hydroxy-1,4-naphthoquinones. The naphthoquinones were prepared from 3-(2-bromophenyl)naphthalen-2-ols, which were obtained by intramolecular aldol condensation of 2-[3-(2-bromophenyl)-2-oxo-propyl]benzaldehydes. Alternatively, benzo[b]naphtho[2,3-d]furan-6,11-diones were

    日期:——
    The direct synthesis of isocoumarin skeletons has been realized through the Rh(III)-catalyzed [3 + 3] annulation of sulfoxonium ylides with iodonium carbenes. The synthetic protocol was constructed efficiently with broad functional group tolerance and mild reaction conditions. This reaction can be formally viewed as the result of C–H activation, carbene insertion and nucleophilic addition processes

  • Annulation Strategies for Benzo[<i>b</i>]fluorene Synthesis:  Efficient Routes to the Kinafluorenone and WS-5995 Antibiotics
    作者:Ghassan Qabaja、Graham B. Jones
    DOI:10.1021/jo0056186
    日期:2000.10.1
    Intramolecular palladium-mediated arylation approaches to benzo[b]fluorenes have been investigated. The methodology has been applied in a short synthesis of tri-O-methylkinafluorenone, providing an effective alternative td Friedel-Crafts-based approaches. During the course of this work, an acid-promoted quinolactonization of naphthoquinones was also developed, providing direct access to either ortho or para isomers as desired. Application of this methodology in syntheses of the antibiotics WS-5995A, WS-5995C, and functional analogues was demonstrated, and antitumoral activity of this class was determined.
