the isolation of eight new sesquiterpenoids named capillosananes S–Z (1–8) and six known sesquiterpenes. The structures of the new compounds were determined on the basis of extensive spectroscopic analysis, including CD effects and Mosher method for the assignment of their absolute configurations. Capillosananes S–U (1–3) presented as the novel carbon skeletons with bicyclo[3,6,0] and bicyclo[4,5,0]
对软珊瑚Sinularia capillosa进行化学检查后,分离出了八种新的倍半萜类,命名为capillosananes S–Z(1 – 8)和六种已知的倍半萜类。在广泛的光谱分析的基础上确定了新化合物的结构,包括CD效应和Mosher方法进行了绝对构型的分配。Capillosananes S-U(1 - 3)呈现为与双环[3,6,0]和双环[4,5,0]系统的新颖碳骨架,而capillosanane V(4)获得了前所未有的三环骨架的特性。Capillosananes W–X(5 – 6)被分配到不寻常的杜绝烷型倍半萜烯中。另外,首次分配了异丁烯-9,14-二醇的立体异构体的绝对构型。
