An enantioselective totalsynthesis of the novel bioactive epoxyquinone natural product (+)-hexacyclinol, exhibiting promising growth inhibiting activity against cancer cell lines, has been accomplished from a readily available chiron derived from the Diels–Alder adduct of cyclopentadiene and p-benzoquinone.

The enantiomerically pure and readily available metabolites 10-12 have been converted over four simple steps into the epoxyquinol derivatives 22-24, respectively. Compounds 23 and 24 or their immediate precursors have been exploited in efficient total syntheses of (-)-bromoxone (ent-1), (-)-epiepoformin (ent-2), (-)-harveynone (4), (+)-panepophenanthrin (6), and (+)-hexacyclinol (9).
