In the context of the preparation of camptothecin and luotonin A analogs, the synthesis of some key keto-precursors and their use in Friedländer condensation are described. This paper also focuses on the stability of these keto intermediates and emphasizes the major differences between indolizinones and pyrroloquinazolinones series. Noteworthy is also the report of some original structures isolated
在喜树碱和荧光素A类似物的制备中,描述了一些关键的酮基前体的合成及其在弗里德兰德缩合反应中的用途。本文还着重于这些酮中间体的稳定性,并强调了吲哚嗪酮和吡咯并喹唑啉酮系列之间的主要区别。值得注意的是,一些实验的副产物也分离出了一些原始结构。
