  • Facile and Efficient Synthesis of Naturally Occurring Carbasugars (+)-Pericosines A and C
    作者:Yoshihide Usami、Marie Ohsugi、Koji Mizuki、Hayato Ichikawa、Masao Arimoto
    DOI:10.1021/ol9008188
    日期:2009.6.18
    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.
  • Studies toward the construction of the allyltrisulfide component in esperamicin-A1 from 5-ketoshikimic acid derivatives: Part 2
    作者:Sandrine Piguel、Gerardo Ulibarri、David S. Grierson
    DOI:10.1016/s0040-4039(98)02400-9
    日期:1999.1
    The MOM protected keto alcohol 7 was successfully converted to the silyl enol ether 4 by reaction with BSA. Reaction of this intermediate with dioxirane led to formation of allylic alcohol 10. Lactone 15 was obtained by reaction of tosylate 14 with the cuprate reagent derived from ethyl bromoacetate. Through a short sequence of reactions this 5-membered lactone was isomerized to the target lactone product 18. (C) 1998 Elsevier Science Ltd. All rights reserved.
  • First Total Synthesis of Antitumor Natural Product (+)- and (−)-Pericosine A:  Determination of Absolute Stereo Structure<sup>†</sup>
    作者:Yoshihide Usami、Isao Takaoka、Hayato Ichikawa、Yusuke Horibe、Syunsuke Tomiyama、Misako Ohtsuka、Yumi Imanishi、Masao Arimoto

    日期:2007.8.1
    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
    已完成(+)-和(-)-pericosine A的第一个全合成,从而能够修订和确定该抗肿瘤天然产物的绝对构型,即甲基(3 S,4 S,5 S,6 S)- 6-氯-3,4,5-三羟基-1-环己烯-1-羧酸酯。该全合成的每一步都以优异的立体选择性进行得很好。关键步骤中的中间体结构通过详细的2D NMR分析得到确认。
