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.

The isolation, structure determination and synthesis of 23{R),24{R)-methylene-:holesterol--a possible biosynthetic precursor of brassicasterol--is described. We had earlier suggested that cyclopropylsterols may be biosynthetic intermediates in the alkylation of marine sterols 2 . In this communicat
tero, fp!?.x A new cyclopropyl-containing sterol papakusterol (22-dehydro-24,26-cyclocholes- arising by a hitherto unknown bios nthetic process, was isolated from six "deep sea" gorgonians and its structure elucidated by Y H-NMR analysis and partial synthesis. Traces of the corresponding A5v7-diene
