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.
开发了一种高效的方法,通过金(III)催化的1,4-亲核加成和随后的氧化反应,有选择性地制备不同的2-氨基-1,4-萘二酮和6-氨基-5,8-喹啉二酮衍生物。在温和条件下,多种一级、二级和芳香胺,以及烯丙胺和2-丁炔基胺均能很好地耐受,产物收率中等至良好。
