The isolation and structure elucidation of marine sterols such as aplysterol (A),2 stelliferasterol (2)3 and strongylosterol (3)' represent the first evidence that bioalkylation5 of -the cholesterol side chain can occur at the terminus (C-27) as well as at the central positions 24 (and thence C-28),

Two new sterols, 26-methylstronqylosterol (3) and 28-methylxestosterol (5), arlSiW from a hitherto unknown quadruple biomethylationsequence, together with the biogenetically important "missing link", durissimasterol (6), were isolated from the Indo-Pacific sponge Strongylophora durissina.
