  • Synthesis of the Pyranonaphthoquinones Dehydroherbarin, (+)-Astropa­quinone B and (+)-Astropaquinone C en Route to Ascomycones A and B
    作者:Margaret Brimble、Andrew Wadsworth、Jonathan Sperry
    DOI:10.1055/s-0029-1218832
    日期:2010.8
    The total syntheses of the pyranonaphthoquinone natural products dehydroherbarin, (+)-astropaquinone B and (+)-astropa­quinone C are described. A late stage oxidation strategy employed for the synthesis of the astropaquinones was not amenable to the conversion of dehydroherbarin into the ascomycones. The syntheses of astropaquinones B and C reported herein constitute the first total syntheses and their absolute stereochemistry was determined to be (1R,3S).
    本文描述了脱氢草霉素(dehydroherbarin)、(+)-星棘醌B((+)-astropaquinone B)和(+)-星棘醌C((+)-astropaquinone C)三种吡喃萘醌天然产物分子的全合成。在合成星棘醌时使用的后期氧化策略,不适用于将脱氢草霉素转化为囊霉醌(ascomycones)。本文报道的星棘醌B和C的合成是它们的首次全合成,且它们的绝对构型被确定为(1R,3S)。
  • Applications of [4+2] Anionic Annulation and Carbonyl-Ene Reaction in the Synthesis of Anthraquinones, Tetrahydroanthraquinones, and Pyranonaphthoquinones
    作者:Shyam Basak、Dipakranjan Mal
    DOI:10.1021/acs.joc.7b01987
    日期:2017.10.20
    5-dienoates, susceptible to isomerization by acids and bases, are suitable for the [4+2] anionic annulation to give 3-(2-alkenyl)naphthoates in regiospecific manner. When combined with intramolecular carbonyl-ene reaction (ICE), the accessibility of the naphthoates culminates in a new synthesis of anthraquinones and diastereoselective synthesis of tetrahydroanthraquinones. This strategy has also resulted in a

  • Synthesis of Two Naphthoquinone Antibiotics, Dehydroherbarin and 6-Deoxybostrycoidin
    作者:Bart Kesteleyn、Norbert De Kimpe
    DOI:10.1021/jo990676g
    日期:2000.2.1
    The synthesis of two naphthoquinone antibiotics, dehydroherbarin (7) and 6-deoxybostrycoidin (5), was accomplished by reaction of 3-acetonyl-2-bromomethyl-6,8-dimethoxy-1,4-naphthoquinone (23) with either triethylamine or ammonia, respectively. This is the first report on their synthesis.

  • Heptaketides from <i>Corynespora</i> sp. Inhabiting the Cavern Beard Lichen, <i>Usnea cavernosa</i>: First Report of Metabolites of an Endolichenic Fungus
    作者:Priyani A. Paranagama、E. M. Kithsiri Wijeratne、Anna M. Burns、Marilyn T. Marron、Malkanthi K. Gunatilaka、A. Elizabeth Arnold、A. A. Leslie Gunatilaka
    DOI:10.1021/np070466w
    日期:2007.11.1
    Two new heptaketides, corynesporol (1) and l-hydroxydehydroherbarin (2), along with herbarin (3) were isolated from an endolichenic fungal strain, Corynespora sp. BA-10763, occurring in the cavern beard lichen Usnea cavernosa. The structures of 1-3 were elucidated from their spectroscopic data. Aerial oxidation of corynesporol (1) yielded herbarin (3). Acetylation of I afforded the naphthalene derivative 4, whereas acetylation of 3 gave the corresponding naphthoquinone 6 and dehydroherbarin (5). All compounds were evaluated for their cytotoxicity and ability to inhibit migration of human metastatic breast and prostate cancer cell lines MDA-MB-231 and PC-3M, respectively. Dehydroherbarin (5) inhibited migration of both cell lines at concentrations not toxic to these cell lines. This is the first report of metabolites from an endolichenic fungus.
