Abstract

Minor pigments of the lacciferid Austrotachardia acaciae Maskell include isoerythrolaccin and the new 7-hydroxyerythrolaccin whose structure was confirmed by synthesis. Severe treatment of certain derivatives of 1, 3-dihydroxyanthraquinone with aluminium chloride has resulted in novel deoxygenation to the 1-hydroxy series. The 1, 2-dimethyl anthraquinones, 3, 6, 8-trihydroxy-1, 2-dimethylanthraquinone and 3, 6, 7, 8-tetrahydroxy-1, 2-dimethylanthraquinone, have been synthesized. Oxidation of the methyl groups has been explored as a possible route to the synthesis of the major pigment from A, acaciae, xantholaccaic acid B.
