An Alternative Synthetic Access to cis-4a-Methyloctahydrophenanthrene, a Biomarker of Sergipe-Alagoas Basin Petroleum in Brazil
cis-4a-Methyloctahydrophenanthrene (1) was prepared in 8 steps (23% overall yield) from 2-bromophenyl)acetic acid (3) and cyclohexane-1,3-dione (6). A highly cis-diastereoselective Michael-type Heck coupling served as the key step in the assembly of the tricyclic skeleton. This compound 1 was used a...
