The reaction of isatoic anhydride (1) with carbon disulfide at room temperature unexpectedly afforded 1,2-dihydro-2-thioxo-4H-3,1-benzothiazin-4-one (2). The use of (13)C-labeled carbon disulfide elucidated that CS(2) was entirely incorporated into the product. (C) 2010 Elsevier Ltd. All rights reserved.
