By following the antifungal activity, four antifungal principles, acetovanillone(1), two new cyclic β-diketones, (2 and 3), and an unknown compound (4), were isolated from wood tar, Pix Pini, which has been used traditionally for the treatment of fungal diseases in Japan. The structures of 2 and 3 were established by synthesis to be 1, 1', 3, 3'-tetraoxo-2, 2'-bicyclopentyl and its 4-methyl derivative, respectively. Chemical reactivities and physical properties of 2 and 3 are also described.
通过跟踪抗真菌活性,我们从日本传统上用于治疗真菌疾病的木焦油 Pix Pini 中分离出了四种抗真菌成分:乙酰香兰酮(1)、两种新的β-环二酮类化合物(2 和 3)以及一种未知化合物(4)。通过合成确定了 2 和 3 的结构,它们分别是 1, 1', 3, 3'-tetraoxo-2, 2'-bicyclopentyl 及其 4-甲基衍生物。此外,还介绍了 2 和 3 的化学反应性和物理性质。
