Two protoilludanes tricoprotoilludanone (1) and tricoilludanlactone (2), a cerapicane tricocerapicanol D (3), an illudane tricoilludin D (4), and a ceratopicane tricoceratopicanone A (5) were isolated from Daedaleopsis tricolor along with a spiroaxane tricospiroaxane (6). Density functional theory (DFT)-based ¹H and ¹³C NMR chemical shift studies verified the hypothesized structures. The absolute configurations of 2, 3, 5, and 6 were established by the ECD spectral comparisons with those based on DFT calculations. Although the absolute configurations of 1 and 4 were not directly discussed with the ECD spectra, structural resemblance to other compounds suggested the (11R)-configuration for 1 and 4. The authors hypothesized that protonated a 6,7-epoxyprotoilludane biosynthesizes a variety of illudane, cerapicane, and ceratopicane frameworks. These were successfully simulated in silico.

两种 protoilludanes tricoprotoilludanone ( 1 ) 和tricoilludanlactone ( 2 )、cerapicane tricocerapicanol D ( 3 )、 illudane tricocerapicanol D ( 4 ) 和ceratopicane tricoceratopicanone A ( 5 ) 与螺环烷三螺环烷 ( 6 )一起从Daedaleopsis tricolor中分​​离出来。基于密度泛函理论 (DFT) 的¹ H 和¹³ C NMR 化学位移研究验证了假设的结构。2、3、5和6的绝对配置通过 ECD 光谱与基于 DFT 计算的光谱比较确定。虽然1和4的绝对构型没有与 ECD 光谱直接讨论，但与其他化合物的结构相似性表明1和4的 (11 R )-构型。作者假设质子化的 6,7-环氧原伊鲁丹可生物合成各种伊鲁丹、角芥烷和角叶烷骨架。这些在计算机上成功模拟。
