Out of options? Even though a systematic approach was chosen, which led to a set of four diastereomeric macrolides modeled around the proposed structure of leiodolide B (see picture), the puzzle concerning the stereostructure of this cytotoxic metabolite derived from a deep‐sea sponge still remains unsolved.
别无选择了吗?尽管选择了一种系统的方法,导致围绕拟议的莱奥多利德B结构(参见图片)建模了四个非对映体大环
内酯类化合物,但有关这种源自深海海绵的细胞毒性代谢物的立体结构的难题仍未解决。
