A novel marine natural product, (+)-aureol (1), was efficiently synthesized starting from the cis-fused decalin derivative 4. The synthetic method features borontrifluoride etherate-promoted rearrangement/cyclization reaction of (+)-arenarol (2) to form (+)-aureol (1) with complete stereoselectivity in high yield. (+)-Arenarol (2) was prepared in an alternative and more efficient manner employing

A total synthesis of the marine spongemeroterpenoid (+)-aureol has been achieved in 12 steps (6% overall yield) from (+)-sclareolide. Key steps of the synthesis include a biosynthetically inspired sequence of 1,2-hydride and methyl shifts, and a biomimetic cycloetherification reaction.

As an important bioactive molecular backbone, drimane meroterpenoids have drawn a great deal of attention from both pharmacologists and chemists. Inspired by the prevalidated success of conformational restriction in the discovery of novel pharmaceutical leads, two distinct tetracyclic drimane meroterpenoids, (−)-pelorol and (+)-aureol, were synthesized from the inexpensive starting material (−)-sclareol
