Abstract
2-Benzoyl-2-phenyl-4,5,6,7-tetrachlorobenzo-1,3-dioxole (1) undergoes Stobbe condensation readily with dimethylsuccinate in the presence of potassium tert-butoxide to give the acid ester (2a), which is converted into benzocyclopentadienone and naphthalene derivatives via two different routes. The in vitro antimicrobial spectra of these compounds were evaluated. Anhydride (3), phenolic acid (5b), carbamate (5c) and hydrazide (5e) are shown to possess high activity against all tested pathogenic gram-negative organisms in addition to Staphylococcus aureus and the tested yeast species.
