Abstract: Three new cyclic peroxides (2-4) have been isolated from the Okinawan marine sponge Plakortis sp., and the structures were elucidated by extensive spectroscopic analyses. The absolute stereochemistries of 2 and 3 were determined by chemical conversion, whereas that of the dioxane ring of 4 was assigned by the modified Mosher’s method.
