A novel and facile method for the synthesis of 4H-cyclopenta[c]pyrrolo[1,2-b] isoquinolin-2(3H)-one has been developed by employing the [2, 3] Stevens rearrangement of methyl N-allyl-N-benzylpyrrolidine 2-carboxylate to methyl 2-allyl-l-benzyl-pyrrolidine 2-carboxylate and acid-lactonisation as key transformations. The synthetic strategy from readily available materials provided a model skeletal analogue
通过使用甲基 N-烯丙基的 [2, 3] 史蒂文斯重排,开发了一种合成 4H-环戊二烯 [c] 吡咯并 [1,2-b] 异喹啉-2(3H)-one 的新型简便方法。 N-苄基吡咯烷 2-羧酸酯到 2-烯丙基-1-苄基-吡咯烷 2-羧酸甲酯和酸内酯化作为关键转化。由现成材料合成的策略提供了头孢菌素的模型骨架类似物,在头孢菌素生物碱的合成中应具有普遍适用性。
