The biosynthetic origins of the dichloroimine group in the stylotellanes A and B 1, 2 have been investigated by incorporation of [ 14 C]-labeled farnesyl isocyanide 7 and farnesyl isothiocyanate 3 into the sponge Stylotella aurantium.
The biosynthetic origins of the isocyanide and isothiocyanate groups in 9-isocyanop upukeanane (2) and 9-isothiocyanatopupukeanane (3) are investigated by incorporation of [ 14 C]-labelled advanced precursors into the sponge Axinyssa n.sp.
Petrosterol, an unusual cyclopropane-containing marine sponge sterol, is shown, unexpectedly, to be derived by SAM biomethylation of 24-methylenaoholesterol via a complex rearrangement process.
Through appropriate labeling experiments, it was shown that the unusual sterol 3B-(hydroxymethyl)-A-nor-Sa-cholest-15-ene ( 1) is generated by ring contraction of dietary cholesterol followed by the introduction of the 15-16 double bond, rather than by ring contraction of 15-dehydrocholesterol (4).
