                                    Birkinshaw, Chambers and Raistrick1 have described stipitatic acid, a metabolite of the mould Penicillium stipitatum, to which, after lengthy examination, they could ascribe no reasonable structure. The evidence they give, however, does seem to indicate a unique structure for the compound. The evidence is as follows:
                                    Birkinshaw、Chambers 和 Raistrick1 已经描述了 stipitatic 酸,一种霉菌 Penicillium stipitatum 的代谢物,经过长时间的检查,他们无法确定合理的结构。然而,他们提供的证据似乎确实表明该化合物具有独特的结构。证据如下:
