Four new prenylindole derivatives, (R)-6-(2,3-dihydroxy-3-methylbutyl)indole (1), (R)-6-(2,3-dihydroxy-3-methylbutyl)indolin-2-one (2), and an unseparated mixture of (Z)-6-(4-hydroxy-3-methylbut-2-en-1-yl)indolin-2-one (3a) and (E)-6-(4-hydroxy-3-methylbut-2-en-1-yl)indolin-2-one (3b) with a ratio of 3 : 2, were isolated from the culture broth of a streptomycete isolated from Ailuropoda melanoleuca feces. Their structures were elucidated on the basis of 1D and 2D NMR spectroscopic techniques. The absolute configuration of 1 was determined by Mosher's method.
从大熊猫粪便中分离得到的一株链霉菌发酵液中分离得到 4 个新的苯并吲哚衍生物：（R）-6-（2,3-二羟基-3-甲基丁基）吲哚（1）、（R）-6-（2,3-二羟基-3-甲基丁基）吲哚啉-2-酮（2），以及（Z）-6-（4-羟基-3-甲基-2-丁烯-1-基）吲哚啉-2-酮（3a）和（E）-6-（4-羟基-3-甲基-2-丁烯-1-基）吲哚啉-2-酮（3b）的混合物（3a 和 3b 的比例为 3:2）。它们的结构是基于 1D 和 2D NMR 波谱技术确定的。通过 Mosher 法确定了 1 的绝对构型。
