Free-radical generated at C-7 position of indole derivative bearing N-(3′-chloroallyl) group prompted a regioselective intramolecular cyclization to furnish pyrroloindolinederivative, through the more favorable 5-exo-trig cyclization mode. The pyrroloindoline compound smoothly rearranged to pyrroloquinoline under mild conditions.
