Abstract
3-Amino-1,2-benzisothiazole-1,1-dioxides (2b-n) have been prepared by heating saccharin (1) and the hydrochlorides of primary and secondary aliphatic amines with phosphorus pentoxide and N,N-dimethylcyclohexylamine at 240 °C. 3-Aminothieno[3,4-d]-isothiazole-1,1-dioxides (6a-c) were similarly prepared from thieno[3,4-d]isothiazol- 3(2H)-one-1,1 -dioxide (6). 31P NMR spectra were obtained of reaction mixtures and reagents. Biological screening of 2 is discussed.
