Description
| - Treatment of N-(α-ketoacyl)anthranilic acids 1 with acetic anhydride and pyridine yields N-acetyl-3-alkylidenebenzoxazepinediones 2. Conducting a series of reactions of compounds 2 with water in warm DMSO and in acidic dioxane at room temperature was always observed the formation of unexpected products of hydrolysis and transacetylation, namely 2-{[2-(acetyloxy)alk-2-enoyl]amino}benzoic acids 3. The results indicate that this transformation occurs through an oxazolidine cyclic intermediate. The reactivity of compounds 2 towards other nucleophiles was also investigated and the results were discussed.
