1. 7,12-Dimethylbenz[a]anthracene is converted by rat-liver homogenates into products with the properties of the 7- and 12-hydroxymethyl derivatives, the 7,12-dihydroxymethyl derivative, the related carboxylic acids and ring-hydroxylated products such as the 8,9-dihydro-8,9-dihydroxy derivative and phenols. Ring-hydroxylated products and products arising from the further oxidation of the hydrox...

Reaction of tetrafluoropyridazine with catechol gives a tricyclic 9,10-dioxa-1,2-diaza-anthracene system by a sequential nucleophilic aromatic substitution ring annelation process, further extending the use of perfluoroheteroaromatic derivatives for the synthesis of unusual polyfunctional heterocyclic architectures. The tricyclic scaffold reacts with amines and sodium ethoxide providing a short...

The reactivity of fluorene, anthracene and fluoranthene under oxidation and reduction conditions has been investigated in this study. This project looks at catalytic and green approaches of converting PAH to less toxic and/or less stable derivatives that are amenable to further degradation. Hydrothermal reactions have been performed at 300 C with pure H2O and Nafion-SiO2 catalyst for oxidation,...

Highly diastereo- and enantioselective conjugate addition of α-substituted nitroacetates to maleimides under base-free neutral phase-transfer conditions was developed for the synthesis of α,α-disubstituted α-amino acid derivatives.

A number of new disubstituted 2,5-thiazolidinone derivatives were synthesized and tested for their antimicrobial activity against Bacillus subtilis (Gram-positive), Pseudomonas aeruginosa (Gram-negative), and Streptomyces species (Actinomycetes). They displayed different degrees of antimicrobial activities or inhibitory actions.
