The parent pyrrolo[3,2,1-ij]quinolin-4-one and pyrrolo[3,2,1-ij]quinolin-6-one ring systems were made by pyrolysis of appropriate acrylates. In the first case, the cyclisation was effected by flash vacuum pyrolysis (FVP) at 950 ËC, in the second case a cyclisation-dehydrogenation was carried out in one step by FVP over a tungsten trioxide catalyst at 525 ËC.
母体吡咯并[3,2,1-ij]喹啉-4-酮和吡咯并[3,2,1-ij]喹啉-6-酮环系统是通过热解适当的丙烯酸酯制成的。第一种情况是在 950 ℃ 下通过闪速真空热解 (FVP) 实现环化,第二种情况是在 525 ℃ 下通过三氧化钨催化剂一步完成环化-加氢反应。
