摘要：

The present work consists of the one pot synthesis of 5,8-dichloro-3-methyl-4H-1,4-benzothiazines by the condensation and oxidative cyclization of 2-amino-3,6-dichlorobenzenethiol with beta-diketones/beta-ketoesters in dimethyl sulfoxide and oxidation behaviour of 4H-1,4-benzothiazines by 30% hydrogen peroxide in glacial acetic acid to 1,4-benzothiazine sulfones. The structure of all the newly synthesized compounds has been confirmed by elemental analysis and spectral studies.
