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
