    • Representative procedure for the synthesis of spiropyrrolidines derivatives 4a: Method A: A solution of the ferrocene-derived dipolarophile 1a (1 mmol), ninhydrin 2 (1 mmol), and sarcosine 3 (1 mmol) was refluxed in 10 mL acetonitrile until the completion of the reaction as evidenced by TLC. The solvent was removed under reduced pressure and the crude product was subjected to column chromatography using petroleum ether: ethyl acetate (4:1) as eluent. The product 4a was then recrystallized from methanol.Method B: A solution of the ferrocene-derived dipolarophile 1a (1 mmol), ninhydrin 2 (1 mmol), and sarcosine 3 (1 mmol) was refluxed in 10 mL toluene using a Dean-stark apparatus. After the completion of the reaction as evidenced by TLC, the solvent was removed under reduced pressure and the crude product was subjected to column chromatography using petroleum ether:ethyl acetate (4:1) as eluent. The product 4a was then recrystallized from methanol.
