A one-pot method for the Sonogashira coupling and cyclization of 2-bromobenzenesulfonamides and terminal alkynes is presented. This method allows access to a variety of substituted benzosultams regioselectively in excellent yields. The reasons for regioselectivity are interpreted through density functional theory (DFT) studies.
