The structures, including stereochemistries, of two fungal metabolites, terremutin hydrate and (-)-terredionol, were shown to be [4R, 5s, 6S]-4, 5, 6-trihydroxy-2-methylcyclohexane-1, 3-dione (III) and [4R, 6R]-(-)-4, 6-dihydroxy-2-methylcyclohexane-1, 3-dione (IV) by correlating them with xylitol and [2R, 4R]-(-)-pentane-1, 2, 4, 5-tetrol, respectively.
通过将两种真菌代谢物--水合特瑞木汀和 (-)-terredionol 与 x 轴相关联,证明了它们的结构(包括立体化学结构)分别为 [4R,5s,6S]-4,5,6-三羟基-2-甲基环己烷-1,3-二酮 (III) 和 [4R,6R]-(-)-4,6-二羟基-2-甲基环己烷-1,3-二酮 (IV) 、3-二酮 (III) 和 [4R,6R]-(-)-4,6-二羟基-2-甲基环己烷-1,3-二酮 (IV),并将它们与木糖醇和 [2R,4R]-(-)-戊烷-1,2,4,5-四醇联系起来。
