Chemical examination of the soft coral Sinularia capillosa resulted in 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] systems, while capillosanane V (4) was characteristic of an unprecedented tricyclic skeleton. Capillosananes W-X (5-6) were assigned to the unusual dumortane-type sesquiterpenes. In addition, the absolute configurations of the stereoisomers of isodaucene-9,14-diol were assigned for the first time.
