A novel rhodium-catalyzed oxidative [5 + 1] annulation of 2-vinylanilines with α-diazocarbonyl compounds for the construction of quinoline-2-carboxylate derivatives has been developed. A series of functional groups such as methyl, methoxy, fluoro, chloro, bromo, cyano, and even thienyl substituents were tolerated well. This methodology has the potential for use in the pharmaceutical industry.
已经开发了新颖的铑催化的2-乙烯基苯胺与α-重氮羰基化合物的氧化[5 +1]环合反应,用于构建喹啉-2-羧酸酯衍生物。很好地耐受了一系列官能团,例如甲基,甲氧基,氟,氯,溴,氰基,甚至噻吩基取代基。这种方法具有在制药工业中使用的潜力。
