Abstract
The present work deals with one pot synthesis of substituted 4H-1,4-be nzothiazines by the condensation and oxidative cyclisation of 2-amino- 5-bromo-3-methylbenzenethiol with beta-diketones/beta-ketoesters in di methyl sulfoxide. The structure of all the synthesized compounds have been characterized by elemental analyses and spectral studies.
