described. The first total synthesis of mirabiquinone A (2,3,5,6,8,10,11,13-octahydroxy-7-methyl-1H-dibenzo[b,h]xanthene-1,4,9,12(7H)-tetraone) produced by the sea urchin Scaphechinus mirabilis is described. This was achieved by cyclization of 6,6′-ethylidenebis(7-hydroxy-2,3-dimethoxynaphthazarin) or its mono- or dimethoxy derivatives and functional group deprotection. The synthesis of methyl analogues
摘要 咪唑醌A(2,3,5,6,8,10,11,13-八羟基-7-甲基-1 H-二苯并[ b,h ]并蒽1,4,9,12(7描述了由海胆Scaphechinus mirabilis产生的H)-四酮。这是通过6,6'-亚乙基双(7-羟基-2,3-二甲氧基萘他沙林)或其单或二甲氧基衍生物的环化和官能团脱保护来实现的。还描述了米拉醌A的甲基类似物的合成。 咪唑醌A(2,3,5,6,8,10,11,13-八羟基-7-甲基-1 H-二苯并[ b,h ]并蒽1,4,9,12(7描述了由海胆Scaphechinus mirabilis产生的H)-四酮。这是通过6,6'-亚乙基双(7-羟基-2,3-二甲氧基萘他沙林)或其单或二甲氧基衍生物的环化和官能团脱保护来实现的。还描述了米拉醌A的甲基类似物的合成。
