An efficient approach is developed to prepare different 2-amino-1,4-naphthalenedione and 6-amino-5,8-quinolinedione derivatives regioselectively by Au(III)-catalyzed 1,4-nucleophilic addition and subsequent oxidation. A wide variety of primary, secondary, and aromatic amines, as well as allylamine and 2-butynylamine are well tolerated under the mild conditions to give products in moderate to good yields.
