Abstract: In this paper new 3-carboxamides of 4-hydroxy-2H-1,2-benzothiazine-1,1-dioxides were synthesized by aminolysis of 4-hydroxy-2-hydro(methyl)-2H-1,2-benzothiazine-3-carboxylic acid ethyl ester-1,1-dioxides with substituted aminopyrimidines or aminotriazines.Their structures were characterized by 1H NMR,IR,MSand elementary analysis.The biological tests indicated that the majority of these compounds showed herbicidal activity and some showed better plant-grownth regulating activity and antiinfammatory activity.

Key words: 4-Hydroxy-2-hydro(methyl)-2H-1,2-benzothiazine-3-carboxylic acid ethyl ester-1,1-dioxide, Aminolysis, Biological activity
