Facile Three-Component Synthesis of Spirooxindolepyrrololine Ring Systems via 1,3-Dipolar Cycloaddition with 1,4-Naphthoquinone
摘要:
1,3-Dipolar cycloadditions involving 1,4-naphthoquinone and an azomethine ylide generated from a-amino acids and isatins have been used in this reaction to afford the pyrrolidine-2-spiro-3'-oxindole 4 or 5 with moderate to excellent yields.
