An efficient one-pot approach for the synthesis of highly substituted pyrrolocoumarin, quinolone, and pyrrolopyridine derivatives has been achieved by palladium acetate catalyzed reaction in DMF through initially formed enamine from cyclic and acyclic ketones and 6-amino-5-bromocoumarin, 6-amino-5-bromo-1-methyl quinolone, and 2-amino-3,5-dibromopyridine, respectively.
通过在DMF中以醋酸钯催化反应的高效一锅法,成功合成了高度取代的吡咯香豆素、喹啉和吡咯吡啶衍生物。这一过程是通过循环和非循环酮以及6-氨基-5-溴香豆素、6-氨基-5-溴-1-甲基喹啉和2-氨基-3,5-二溴吡啶初步形成的烯胺实现的。
