achyrantifolia (Verbenaceae) and originally assigned as 8-hydroxy-4,9-dihydronaphtho[2,3-b]furan-4,9-dione 1a but its structure was later revised to 5-hydroxy-4,9-dihydronaphtho[2,3-b]furan-4,9-dione 2a. The regiospecific synthesis of diodantunezone 2a and its methyl ether, 5-methoxy-4,9-dihydronaphtho[2,3-b]furan-4,9-dione 2b, is described. The preparation of two 2-ethylfuronaphthoquinones 14a and 14b
Diodantunezone首先从马Lan丹(马鞭草科)中分离出来,最初分配为8-hydroxy-4,9-dihydronaphtho [2,3 - b ] furan-4,9-dione 1a,但后来将其结构修改为5-hydroxy-4 ,9-二氢萘并[2,3- b ]呋喃-4,9-二酮2a。描述了地丹单酮2a及其甲基醚5-甲氧基-4,9-二氢萘并[2,3 - b ]呋喃-4,9-二酮2b的区域特异性合成。还描述了两个2-乙基呋喃萘醌14a和14b的制备。已显示所有四个醌对三种细胞系均具有细胞毒活性(1.3–17.4μmoldm -3)。
