| Abstract: | The 13C nmr spectra of some 4-hydroxy-2H-1,2-benzothiazine 1,1-dioxides I have been recorded and analyzed. Spectroscopic assignments were made on the basis of chemical shift theory, APT and fully coupled 13C nmr spectra. Spectral data support the enolic structure of these compounds. |
