The Pd-catalyzed reaction between 3-acetylamino-2-bromo-1,4-naphthoquinones and CuI acetylides prepared in situ gave 3-acetylamino-2-alkynyl-1,4-naphthoquinones, which were transformed into benz[f]indole-4,9-dione and benzo[g]quinoline-5,10-dione derivatives.
钯催化的3-乙酰氨基-2-溴-1,4-萘醌与原位制备的CuI炔化物之间的反应,生成了3-乙酰氨基-2-炔基-1,4-萘醌,这些产物随后被转化为苯并[f]吲哚-4,9-二酮和苯并[g]喹啉-5,10-二酮衍生物。
