MINOR AND TRACE STEROLS IN MARINE INVERTEBRATES 40. STRUCTURE AND SYNTHESIS OF AXINYSSASTEROL, 25-METHYLFUCOSTEROL AND 24-ETHYL-24-METHYLCHOLESTEROL--NOVEL SPONGE STEROLS WITH HIGHLY BRANCHED SIDE CHAINS

The isolation, structure determination and synthesis of three novel sterols with unusual side chains is reported.A consistent scheme is proposed which accounts for the biosynthesis of all major and minor sterols in this sponge.

The composition of two steroid fractions from the Australian sponge Trachyopsis sp. have been investigated.The fractions of steroid sulfates consisted of the the trisulfates of halistanol (76percent) and of 24-isopropyl-5α-cholest-22-ene-2β,3α,6α-triol (20percent).In the sterol fraction, axinyssasterol (64percent) and 24-isopropyl-5β-cholest-22Z-en-3-ol (30percent) were identified.
