A number of ethyl 3H-pyrrolo[2,3-c]quinoline-2-carboxylates have been prepared directly by condensation of ethyl azidoacetate with 4-formylquinolines, available from o-(1-methylethenyl)aniline by sequential treatment with acid chlorides, phosphorus oxychloride and benzeneseleninic anhydride. This methodology has also been used to synthesize 2,2′-bis(ethoxycarbonyl)-4,4′-bi-3H-pyrrolo [2,3-c]quinoline and 1,4-bis(2-ethoxycarbonyl)-3H-pyrrolo[2,3-c]quinolin-4-yl benzene.
一些乙基3H-吡咯并[2,3-c]喹啉-2-羧酸酯已经通过将乙基叠氮乙酸酯与4-形式基喹啉直接缩合制备而成,这些4-形式基喹啉可通过将o-(1-甲基乙烯基)苯胺依次处理酸氯化物、磷氧氯化物和苯硒酸酐获得。这一方法论也被用于合成2,2′-双(乙氧基羧酸酯)-4,4′-双-3H-吡咯并[2,3-c]喹啉和1,4-双(2-乙氧基羧酸酯)-3H-吡咯并[2,3-c]喹啉-4-基苯。
