Article abstract of DOI:10.1016/0040-4039(92)88184-7

Two hexaprenylhydroquinone derived disulfates, shaagrockol B and C (1 and 2) were isolated from the Red Sea sponge Toxiclona toxius (Levi, 1958). The structure of these two new hexaprenoid, antifungal metabolites was determined by spectroscopic methods, mainly 2D-NMR measurements as well as chemical modifications. Ozonolysis of compound 2 afforded compound 1 and the acid catalysed rearrangement of 1, leading to compounds 3 and 4, has been elucidated.
