An efficient one-pot synthesis of substituted quinolines from alpha-arylamino ketones in the presence of PBr3 in DMF has been developed. This general protocol provides a novel and facile access to substituted quinolines by sequential Vilsmeier-Haack reaction, intramolecular cyclization and aromatization reactions of alpha-arylamino ketones. PBr3 plays a dual role in the quinoline synthesis: as a key
已经开发出一种在 DMF 中 PBr3 存在下从 α-芳基氨基酮高效一锅法合成取代喹啉的方法。该通用协议通过顺序 Vilsmeier-Haack 反应、分子内环化和 α-芳基氨基酮的芳构化反应,提供了一种新颖且简便的方法来获取取代的喹啉。PBr3 在喹啉合成中起着双重作用:作为 Vilsmeier 试剂 (PBr3/DMF) 的关键组分和还原剂。
