The 5-endo-dig iodocyclization of propargylic alcohols followed by a 1,2-shift provided rapid access to 2-iodoindolizinones, while the 5-endo-trig iodocyclization of allylic alcohols and subsequent dehydroiodination and 1,2-shift led to indolizinones. A number of highly substituted indolizinones were constructed under these mild reaction conditions.
