cycloaddition and oxa-di-π-methane rearrangement reactions as key steps. Compound 3 is an advanced intermediate associated with several previously reported total syntheses of the sesquiterpenoid natural products (−)-hypnophilin (1) and (−)-coriolin (2). Related chemistry has provided the tetracyclic compound 5, another established precursor to (−)-coriolin (2).
