Two terphenyl quinones were synthesized for a structural study on a naturally occurring biologically active terphenyl quinone. 3-Methoxy-5,6-diphenylcyclohexa-3,5-dien-1,2-dione, a possible structure proposed by our analysis of the NMR spectra, was synthesized by Suzuki-Miyaura coupling and subsequent oxidation of the resulting substituted phenol, although not being identical to the natural product
合成了两个三联苯醌,用于对天然存在的生物活性三联苯醌的结构研究。Suzuki-Miyaura偶联并随后氧化生成的取代苯酚,合成了3-甲氧基-5,6-二苯基环己-3,5-二烯1,2-二酮,这是我们对NMR光谱分析提出的一种可能的结构,尽管与天然产品不同。从市售的2,5-二苯基-1,4-苯醌分三步合成了最近分离出的3-甲氧基-2,5-二苯基环己-2,5-二烯-1,4-二酮,总收率良好,并且它的NMR谱图与天然产物的谱图相同。
