Synthesis and characterization of some sulphonamidic compounds, derivatives of 4-chloro-3- (N-alkyl/ aril-sulphonamido)-benzoic acid, with potential biologic activity

摘要

Many sulphonamidic compounds presenting a broad biological activity spectrum are known, including pharmaceutical substances, fungicide, and herbicide or insecticide activity derivatives. This paper presents the synthesis of some 4―chloro―3―(N―alkyl/aril-sulphonamido)-benzoic acid compounds, with a potential biological activity. The choice of these compounds was made after taking in consideration the existence of halogeno ―benzoie based herbicides, the biological activity of p―amino benzoic acid and the herbicide activity presented by 2―amino―benzothiazoles compounds.
