A convenient and efficient two-step route to 6H-Isoindolo[2,1-a]indol-6-ones has been developed starting from o-nitrobenzaldehydes. The methodology involves Wittig reaction followed by tandem reductive cyclization–lactamization. A series of isoindoloindolones incorporating different substituents on the indole nucleus has been prepared.
以
邻硝基苯甲醛为原料,开发了一种便捷高效的两步法制备 6H-异
吲哚并[2,1-a]
吲哚-6-酮。该方法涉及 Wittig 反应,然后是串联还原环化 - 内酰胺化。已经制备了一系列在
吲哚核上结合不同取代基的异
