A gold-catalyzed three-component coupling reaction (A3 reaction) was developed as an efficient approach for the synthesis of challenging 2, 4-disubstituted quinoline derivatives. Compared to previously reported Cu/Au bi-catalyst system, this protocol enables achieving A3 reaction only in the presence of triazole-gold catalyst. Notably, 4-alkyl substituted or 2-alkyl substituted quinoline derivatives were obtained with good yields, which highlighted the unique advantage of this new strategy.
一种金催化的三组分偶联反应(A3反应)被开发为一种合成具有挑战性的2,4-二取代喹啉衍生物的有效方法。与先前报道的铜/金双催化剂体系相比,该方法仅在三唑-金催化剂存在下就能实现A3反应。值得注意的是,4-烷基取代或2-烷基取代的喹啉衍生物能以良好的产率得到,这突出了这种新策略的独特优势。
