Polyprenyl derivatives from the sponge Ircinia spinosula

open access: yesTetrahedron, 1972
Abstract Unsubstituted prenylated benzoquinones, a novel group of terpenoid quinones, the corresponding quinols, together with the hydroxylated 2-octaprenyl-quinol (VII) have been identified in the marine sponge Ircinia spinosula. From the same sponge we have also isolated the prenylated furan derivatives XI, XII and XIII, named furospinosulin-1, -2 ...
