  • Preparation of Naphthoquinone Derivatives from Plumbagin and Their Ichthyotoxicity.
    作者:Kazuhito OGIHARA、Rieko YAMASHIRO、Matsutake HIGA、Seiichi YOGI
    DOI:10.1248/cpb.45.437
    日期:——
    Various naphthoquinone derivatives were prepared from a natural product, 5-hydroxy-2-methyl-1, 4-naphthoquinone (plumbagin); these were mostly substituted at C-3 through carbon-carbon bond formation mediated by a metal-based oxidant such as lead tetraacetate in the presence of various carboxylic acids. The halogenated compounds showed stronger ichthyotoxicity than plumbagin, but other derivatives were less active.
    各种萘醌衍生物是从天然产物5-羟基-2-甲基-1,4-萘醌(铅醌)中制备的;这些衍生物主要通过金属氧化剂(如醋酸铅四乙酯)在多种羧酸存在下,通过碳-碳键形成在C-3位进行取代。卤素化化合物的鱼毒性比铅醌更强,但其他衍生物的活性较低。
