N-(α-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-(α-ketoacyl)anthranilic acids in the preparation of anthranilic acid hydrochlorides.
使用对二碘酸(H 5 IO 6)或高碘酸钠(NaIO 4),通过3-羟基喹啉-2,4(1 H,3 H)-二酮的氧化开环来制备N-(α-酮酰基)邻氨基苯甲酸。描述了反应条件的优化以及在邻氨基苯甲酸盐酸盐的制备中N-(α-酮酰基)邻氨基苯甲酸的利用。
