PROCESS FOR THE PREPARATION OF ANTHRANILIC ACIDS SUBSTITUTED IN POSITION 3 AND / OR 5. |
| abstract |
Anthranilic acids substituted in the 3- and/or 5-position are valuable intermediates for the production of agricultural chemicals. These substituted anthranilic acids can be obtained in good yield without undesirable isomeric byproducts by the oxidative ring-opening of dihydroquinolin-4-ones or quinolin-2,4-diones with t-butyl hydroperoxide in the presence of a base. |
