  • Total Synthesis of Polycavernoside A, A Lethal Toxin of the Red Alga <i>Polycavernosa </i><i>t</i><i>sudai</i>
    作者:Paul R. Blakemore、Cindy C. Browder、Jian Hong、Christopher M. Lincoln、Pavel A. Nagornyy、Lonnie A. Robarge、Duncan J. Wardrop、James D. White
    DOI:10.1021/jo0503862
    日期:2005.7.1
    Two approaches to the synthesis of the aglycon 120 of polycavernoside A (1) were developed, only one of which was completed. The successful "second-generation" route assembled the aglycon seco acids 102 and 106 via Nozaki-Hiyama-Kishi coupling of aldehyde 70, prepared from methyl (S)3-hydroxy-2-methylpropionate (72) and (S)-pantolactone (73), with vinyl bromide 71. The latter was obtained from a sequence which commenced from the silyl ether 24 of 3-hydroxypropionaldehyde and entailed cyclization of (Z)-zeta -hydroxy-alpha,beta-unsaturated ester 82. Regioselective Yamaguchi lactonization of trihydroxycarboxylic acids 102 and 106 and subsequent functional-group adjustments led to macrolactone 120, to which the fucopyranosylxylopyranoside moiety was attached. Stille coupling of the glycosidated aglycon 128 with dienylstannane 129 furnished polycavernoside A in a synthesis for which the longest linear sequence was 25 steps. The overall yield to lactone 120 was 4.7%.
  • Polycavernoside A: The Prins Macrocyclization Approach
    作者:Sang Kook Woo、Eun Lee
    DOI:10.1021/ja1009579
    日期:2010.4.7
    An intramolecular Prins macrocyclization reaction was successfully employed in the synthesis of polycavernoside A.
  • Total Synthesis of the Marine Toxin Polycavernoside A via Selective Macrolactonization of a Trihydroxy Carboxylic Acid

    DOI:10.1246/cl.1995.855
    日期:1995.9
    Combination of the sugar and tetrahydropyran parts of polycavernoside-A, which has been isolated as one of toxic principles from the red alga Polycavernosa tsudai, revealed the whole relative configuration of the compound from the spectral data.

  • Total Synthesis of (−)-Polycavernoside A: Suzuki–Miyaura Coupling Approach
    作者:Yusuke Kasai、Takanori Ito、Makoto Sasaki
    DOI:10.1021/ol301278e
    日期:2012.6.15
    A total synthesis of ()-polycavernoside A, a marine lethal toxin isolated from the edible alga Gracilaria edulis, has been achieved via a convergent approach. The synthesis is highlighted by catalytic asymmetric syntheses of the two key fragments and their union through Suzuki–Miyaura coupling and Keck macrolactonization.
