title: Enantioselective iodolactonization of allenoic acids.
abstract: An enantioselective iodolactonization reaction of allenoic acids has been developed using a trisimidazoline catalyst and I2. Our mechanistic study suggests the involvement of a π-allyl cation intermediate in this reaction system.
