5-endo-dig Cyclizations of Homopropargylic Sulfonamides: A New Route to 2,3-Dihydropyrroles and β-Iodopyrroles.

-The synthesis of dihydropyrroles (VIII) by 5-endo-dig iodocyclization of readily obtainable sulfonamides (VII) and their conversion into β-iodopyrroles (IX) via base-catalyzed elimination of sulfinic acid is described. -(KNIGHT, D. W.; REDFERN, A.
