    • General procedure for the synthesis of N-benzylpyrroles. To an aqueous solution of β-cyclodextrin (1.0 mmol of β-CD in 5 mL of water), IBX (2.0 mmol), N-benzylpyrrolidine (1.0 mmol) was added while stirring, and stirring was continued for the stipulated reaction time as shown in the Table at room temperature. After completion of reaction as indicated by TLC, the reaction mixture was extracted with ethyl acetate (3 × 5 mL), the combined organic layers were washed with saturated brine solution, dried and concentrated in vacuum. The crude product was purified by column chromatography on Silica gel using hexane/ethyl acetate (9:1) as an eluent
