Autor: AS Krauss, WC Taylor

Publikováno v: Australian Journal of Chemistry. 45:925

The synthesis of (2RS,3SR)-4-(4-hydroxy-3,5-dimethoxyphenyl)-2,3-dimethyl-1-(3,4,5-trimethoxypheny1)butan-1-one (9) is described. Monophenolic oxidative coupling of (9) did not give any useful result. Oxidation of the derived acetoxy compound (18) by

Intramolecular non- phenolic coupling of (2RS,3SR)-1,4-bis(4-benzyloxy-3,5-dimethoxyphenyl)-2,3-dimethylbutan-1-one (6) failed. Oxidation of the derived butane(9) gave the aryltetralin (14) in low yield.

Intramolecular Oxidative Coupling of Aromatic Compounds. I. Oxidation of Diphenolic Substrates

Autor: AS Krauss, WC Taylor

Publikováno v: Australian Journal of Chemistry. 44:1307

The synthesis of (2RS,3SR)-1-(3,5-dihydroxy-4-methoxyphenyl)-(4-hydroxy-3,5-dimethoxy-phenyl)-2,3-dimethylbutan-1-one (26) is described. Diphenolic oxidative coupling of (26) did not produce a eupodienone -type product. An aryltetralin derivative was
