Die Methoxid-katalysierteUmlagerungvonGrevillin-Derivaten 2 liefert Terphenylchinone 1 in hohen Ausbeuten. Die Flexibilität dieser Methode wird an der Synthesevon Polyporsäure (1a), Ascocorynin (1b) und Leucomelon (1m) demonstriert, sowie vonTerphenylchinonen und Terphenylchinon-Analogen, die 2,4,5-Trihydroxyphyenyl-, 4-Nitrophenyl-, 2,4-Dichlorphenyl-, Naphthyl-, Indolyl- und Styryl-Reste enthalten

Two sequential Suzuki coupling reactions have been developed for efficient synthesis of synthetically and biologically important 3,6-disubstituted 2,5-dioxybenzoquinone architectures in a highly chemoselective controlled manner. The method serves as a key step in the total synthesis of leucomelone in three steps and in 61% overall yield.
