A general synthesis of (±)-dibenzocyclooctadiene lignans

We have established a new general synthesis for (±)- dibenzocyclooctadiene lignans, including (±)-schizandrin (1a), (±)-gomisin A (1b), (±)-isoschizandrin (3a), and (±)-isogomisin A (3b), via the spiro- dienone ethers E- and T-11 as the key intermediates, prepared from the corresponding bisarylbutanol derivatives E- and T-10 by the oxidation with Weitz' aminium salt, tris(4-bromophenyl)aminium hexachloroantimonate (BAHA). These syntheses consist of 13 steps from the phenylpropanone 5.

Intramolecular Oxidative Coupling of Aromatic Compounds. V. para-para Diphenolic Oxidative Coupling as a Possible Route to the Eupodienone Skeleton

The synthesis of (2RS,3RS)-1,4-bis(4-hydroxy-3,5-dimethoxyphenyl)-2,3-dimethylbutan-1-one (9) is described.Diphenolic oxidative coupling of (9) gave the unstable dienone (24), which decomposed in methanol to give what is believed to be the acetal (26).Syn
