We report the development of a straightforward, waste-reducing, environmentally friendly, FeIII-catalyzed domino aza-Michael/aldol/aromatization reaction in the presence of water to access high-value functionalized quinolines by using 2-aminobenzophenones and ethyl buta-2,3-dienoate as starting compounds. The tangible advantages, that is, the utilization of commercially available and/or easily accessible
我们报告了一种直接、减少废物、环境友好、Fe III催化的多米诺氮杂-迈克尔/醇醛/芳构化反应的开发,该反应在水存在下通过使用 2-氨基二苯甲酮和乙基丁二酮获得高价值的官能化喹啉,3-二烯酸酯作为起始化合物。明显的优势,即利用市售和/或易于获得的底物、简单、温和的反应条件以及水作为溶剂的应用,使得这种三步多米诺骨牌工艺变得绿色,并且对于直接构建多米诺骨牌非常有吸引力。多种高功能化喹啉,产率高达 78%。
