    • General Procedure To a stirred solution of indole (1 mmol) in DCE (3 mL) were added the N-tosylazetidine (1 mmol) and InBr3 (0.1 mmol, The resulting mixture was stirred at reflux temperature for the appropriate time (Table 1, After complete conversion as indicated by TLC, the solvent was removed by evaporation, and the residue was diluted with H 2O and extracted with EtOAc (2 x 10 mL, The combined organic layers were dried over anhyd Na2SO4 and concentrated in vacuo. The resulting product was purified by column chromatography on SiO2 (Merck, 100-200 mesh) using EtOAc-hexane (3:7) as eluent to afford pure 3-alkenyl indole derivative.
