The reaction of 1,4-naphthoquinone (1) with 2,5-dimethylpyrroles (7a-7d) gives only 3-(1,4-naphtho-quinonyl)-2,5-dimethylpyrroles. Extending the reaction to other quinones: 5-hydroxy-1,4-naphthoquinone (2), 1,2-naphthoquinone (3), quinoline-5,8-dione (4) and quinoxaline-5,8-dione (5), of which nothing was known, allows the synthesis of new pyrrolylquinones.
1,4-萘醌(1)与2,5-二甲基吡咯(7a-7d)的反应仅产生3-(1,4-萘醌基)-2,5-二甲基吡咯。将反应扩展至其他醌:5-羟基-1,4-萘醌(2),1,2-萘醌(3),喹啉5,8-二酮(4)和喹喔啉-5,8-二酮(5) ,其中什么都不知道,可以合成新的吡咯基醌。
