Abstract Derivatives of anthranilicacid exhibit a range of useful biological activities. Herein we describe an efficient synthetic route to 1,3-benzothiadiazin-4(3H)-one 2-oxides via copper-catalyzed N-arylation of sulfonimidamides followed by cyclization. Such 1,3-benzothiadiazin-4(3H)-one 2-oxides can be viewed as novel anthranilicacid derivatives. Derivatives of anthranilicacid exhibit a range of
