| Isatoic Anhydride Usage And Synthesis |
| Synthesis | Isatoic Anhydride is synthesized from indole (9a) by stirring in a 4:1 mixture of DMF/H2O for 16 h at room temperature. 1 H NMR (DMSO-d6): δ11.73 (s, br., 1H), 7.92 (d, J = 7.8 Hz, 1H), 7.74 (t, J = 7.8 Hz, 1H), 7.26 (t, J = 7.8 Hz, 1H), 7.16 (d, J = 7.8 Hz, 1H). |
| Chemical Properties | BEIGE TO BROWN POWDER |
| Uses | Isatoic anhydride is a potent inactivator of α-chymotrypsin and inactivates stoichiometrically. Isatoic Anhydride is an important compound in the preparation of serine protease inhibitors. |
| Definition | A bicyclic molecule composed of a benzene ring attached at the oand mpositions to a heterocyclic ring. It forms useful anthranilic acid derivatives by reaction with hydrogen. |
| Preparation | Phosphorus tribromide (0.035 mol) was added to a solution of N-carbethoxy- or N-carbobenzoxy-anthranilic acid (0.1 mol;prepared by coupling anthranilic acid with the corresponding carbalkoxy chloride in the usual way) in anhydrous diethyl ether (100 mL). After 24 h at room temperature, isatoic anhydride had separated as a microcrystalline product. It was collected by filtration, washed with dry diethyl ether, and recrystallized from ethanol. Yield ca. 90%. |
| Flammability and Explosibility | Non flammable |
| Purification Methods | Recrystallise it from EtOH or 95% EtOH (30mL/g) or dioxane (10mL/g) and dry it in a vacuum.
