The established metabolites of Aspergillus versicolor include numerous xanthones and anthraquinones, and a substituted imide1}. Recently Dhar and Bose2) reported the isolation of a new antifungal antibiotic, named versicolin, from the culture nitrate of a strain of A. versicolor. Low yielding cultures of A. versicolor could be regenerated by mutagenic treatment3*. Versicolin was notable because...
The aerobic organocatalytic oxidation of alcohols was achieved by using water-soluble sodium anthraquinone sulfonate. Under visible-light activation, this catalyst mediated the aerobic oxidation of alcohols to aldehydes and ketones. The photo-oxyfunctionalization of alkanes was also possible under these conditions.
A novel cysteine-incorporated anthraquinone derivative was synthesized, and its molecular structure was determined by X-ray crystal analysis. Each mercapto group was located separately and did not form a disulfide bond, and hydrogen bondings and π-π interaction were observed from the packing structure.
