  • Synthesis of Pyragonicin
    作者:Daniel Strand、Tobias Rein
    DOI:10.1021/ol050997g
    日期:2005.6.1
    [structure: see text] A stereocontrolled convergent synthesis of the annonaceous acetogenin pyragonicin (1) is presented. The key intermediates were accessed using asymmetric Horner-Wadsworth-Emmons (HWE) methodology. A reagent controlled zinc-mediated stereoselective coupling, joining the two highly functionalized intermediates 3 and 4, then provided the core structure.

    Pyranicin (1) and pyragonicin (2) are the first mono-tetrahydropyran annonaceous acetogenins, and goniotrionin (3) possesses an unusual hydroxylated-allylic moiety. 1–3 were isolated from the bark of Goniothalamus giganteus using activity-directed fractionation with the brine shrimp lethality test. Both 1 and 2 are selectively cytotoxic against the pancreatic cell line (PACA-2) in a panel of six human

  • Convergent Synthesis of Pyragonicin
    作者:Shunya Takahashi、Yayoi Hongo、Narihito Ogawa、Hiroyuki Koshino、Tadashi Nakata
    DOI:10.1021/jo060970q
    日期:2006.8.1
    This paper describes a second-generation synthesis of an antitumor tetrahydropyran ( THP) acetogenin, pyragonicin. The key step involved an olefin cross-metathesis between the THP segment and the terminal gamma-lactone residue. The coupling reaction in the presence of Grubbs' second-generation catalyst resulted in an unseparable mixture of a desired coupling product and its one-carbon eliminated product while the use of Grubbs' first-generation catalyst afforded the former exclusively. A novel MOM-migrating reaction found in a cyclization reaction is also discussed.

    asymmetric HWE reactions, including the desymmetrization of a meso-dialdehyde and a parallel kinetic resolution of a racemic aldehyde. A stereoconvergent Pd-catalyzed substitution serves to install the C4 stereocenter in protected form with different orthogonal protective groups. A divergent strategy to form 1,4- and 1,6-diols, employing stereoselective Zn-mediated alkynylations, is used for completion

  • Total Synthesis of the Proposed Structure for Pyragonicin
    作者:Shunya Takahashi、Narihito Ogawa、Hiroyuki Koshino、Tadashi Nakata
    DOI:10.1021/ol0508126
    日期:2005.6.1
    The total synthesis of acetogenin 1 reported for pyragonicin and its 10-epimer 32 is described. The common THP ring system was stereoselectively constructed through a SMI2-induced reductive cyclization of beta-alkoxy acrylate 5 followed by Mitsunobu inversion, and each chiral center at C-10 was created by Brown's asymmetric allylation. Compound 1 had spectroscopic data consistent with that of natural pyragonicin, but a different optical rotation.
