Neighboring group participation by sulfonamido nitrogen.
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.
