title: Neighboring group participation by sulfonamido nitrogen.
abstract: The ability of sulfonamido nitrogen to enter into neighboring group participation was established in two different reaction settings. The first was uncovered during the bromination of benzodiazocine 8 in dichloromethane at 0 degrees C, and the second during the base treatment of 15a en route to allene 18.
