title: Hypervalent iodine-triggered transformation of homopropargyl sulfonamides into dihalo-2,3-dihydropyrroles.
abstract: A novel hypervalent iodine-triggered hydroamination of homopropargyl sulfonamides with copper halides to obtain dihalo-2,3-dihydropyrroles was efficiently developed. The reaction can provide access to chloro/bromo-cyclization extended from iodocyclization to prepare potentially useful halogenated building blocks for drug development with broad functional group tolerance and high yield yet in a short time.
