Synthesis of triaromatic steroid hydrocarbons methylated at position 2, 3 or 6: molecular fossils of yet unknown biological origin
Résumé
C21-29 triaromatic steroid hydrocarbons bearing a methyl group at unusual positions 2, 3 or 6 have been synthesized from pregnenolone, cholesterol or stigmasterol via stera-3,5-dienes. Their occurrence in various sedimentary rocks and petroleums suggests the presence of yet unknown biological precursors.
