摘要
N-(alpha-Ketoacyl)anthranilic acids were prepared by oxidative ring opening of 3-hydroxyquinoline-2,4(1H,3H)-diones by using paraperiodic acid (H5IO6) or sodium periodate (NaIO4). The optimisation of the reaction conditions is described as well as the utilisation of N-(alpha-ketoacyl)anthranilic acids in the preparation of anthranilic acid hydrochlorides.
