title: Iodobenzene-catalyzed intramolecular oxidative cyclization reactions of δ-alkynyl β-ketoesters.
abstract: Iodobenzene is shown to catalyze the 5-exo-dig cyclization of δ-alkynyl β-ketoesters under oxidative conditions that generate hypervalent iodine species in situ. The cyclopentane products contain adjacent quaternary and tertiary stereocenters which are generated with excellent diastereoselectivity.
