A novel synthesis of 1,4-benzothiazin-3-ones was developed from Cu-catalyzed coupling of readily available substituted 2-iodoanilines with 2-mercaptoacetate. The new method offers clear advantages over existing approaches for its one-step simple operation, wider reaction scope, and moderate to excellent isolated yields. (C) 2013 Elsevier Ltd.
