Kurospongin (1~), a new C21 furanoterpene having ichthyotoxic and feeding-deterrent properties has been isolated from a marinesponge,Spongia sp. The gross structure was deduced from the spectroscopic data and the absoluteconfiguration by applying the Horeau method to a derivative prepared by the reaction of1~with ethylmagnesium bromide.
