    • Typical procedure: To a flask was added CH2Cl 2 (1OmL, I2 (0.1 mmol, 0.254 g) and benzaldehyde (4mmol, 0.424 g, The resulting solution was stirred for 5 min at room temperature (20 °C, Then, pyrrole (4 mmol, 0.268 g) was added and the mixture was stirred for another 30 min. Upon completion, the mixture was treated as described in Method A or Method B. Method A: The mixture was decanted into a dish charged with 2-g silica gel and mixed uniformly (no massive pellet, It was then put into an oven for 15 min at 200 °C. After being cooled to room temperature, the silica gel charged with the reaction mixture was purified by column chromatography (silica gel; dichloromethane/petroleum ether, 1:3) to give 4 in 41% yield. Method B: The mixture was concentrated under reduced pressure and the residue was applied on a preparative silica gel TLC plate and developed with 20% ethyl acetate in petroleum ether. The zone corresponding to 3 on the develo
