Together with the previously described cacospongionolide B (1) and cacospon
gionolide F (2) a new C-21 terpene (3), related to cacospongionolide B has
been isolated from the sponge Fasciospongia cavernosa, collected in the Aeg
ean Sea. The structure and relative stereochemistry of the new compound, we
re proposed on the basis of spectroscopic data. (C) 1999 Elsevier Science L
