The carcinogen and mutagen, 1-aminoanthracene, was efficiently metabolized by the fungal strain Beauveria bassiana ATCC 7159 to yield three new metabolites identified as 1-acetamido-5-[(4′-O-methyl-β-d-glucopyranosyl)oxy]anthracene, 1-acetamido-8-[(4′-O-methyl-β-d-glucopyranosyl)oxy]anthraquinone, and 1-acetamido-6-[(4′-O-methyl-β-d-glucopyranosyl)oxy]anthraquinone, together with 1-acetamidoanthracene and 1-acetamidoanthraquinone. Formation of these metabolites suggests that the metabolic pathways of 1-aminoanthracene in B. bassiana ATCC 7159 involve acetylation, oxidation, hydroxylation, and O-methylglucosylation.

Silica-supported boric acid (H3BO3-SiO2) has been established as a green, efficient and recyclable catalyst for the synthesis of dihydropyrimidin-2-ones, bis(indolyl)methanes, and acetylation of alcohols, phenols, amines and thiols under solvent free conditions. The main features of the present method include clean reaction, mild conditions, low loading of environment friendly catalyst and easy workup procedure. The catalyst can be recycled at least five times without any significant loss in activity.
SOME RELATIONSHIPS IN THE SYNTHESIS OF BIARYLS FROM HALOGENOANTHRAQUINONES

The effects of the solvent and the concentration of the reagents on the reaction path and on the results of the synthesis of biaryls from halogenoanthraquinones were investigated for the case of the reaction of 1-chloro-4-benzoylaminoanthraquinone with copper.The use of concentrated reaction mixtures and of donating aprotic dipolar solvents with copper-aryl halide ratios slightly exceeding an equimolar ratio leads to a reduction in the induction period and to an increase in the yield of the biaryls.This explained by interaction between the copmonents of the metal-aryl halide-solvent complex.
