摘要
以α-(1,2-亚乙基)酰胺和端炔发生[4+1]环合反应,高效合成了一系列螺环类吡咯啉-2-酮类化合物,其结构经^(1)H NMR,^(13)C NMR和HR-MS(ESI)表征,并对该反应机理进行了探讨。该合成方法具有底物适用范围广泛,操作简单,条件温和以及收率高等优点。
A series of spirocyclic pyrroline-2-one compounds were obtained via[4+1]annulation ofα-(1,2-ethylene)amides and terminal alkynes,and the structures of target compounds were characterized by ^(1)H NMR,^(13)C NMR and HR-MS(ESI).Moreover,a mechanism for the reaction was proposed.The synthetic method has the advantages of extensive substrates,simple operation,mild conditions and high yield.
