title: Benzoxazolone-5-sulphonanilides, 1-(benzoxazolone-5'-sulphonyl)-benzotriazoles and 4-hydroxy-3,2'-diaminobenzenesulphonanilides with antiviral activity.
abstract: benzoxazolone-5-(2'-nitro)-sulphonanilides were synthesized by acylation of o-nitroanilines with benzoxazolone-5-sulphochloride or 3-methylbenzoxazolone-5-sulphochloride. The nitro group in these compounds was subjected to reduction and the resulting amino derivatives were cyclysed to yield the corresponding 1-(benzoxazolone-5'-sulphonyl)-benzotriazoles. Decyclization of the oxazolone cycle of benzoxazolone-5-(2'-amino)-sulphonanilides resulted in 4-hydroxy-3,2'-diaminobenzenesulphonanilides. In vitro testing of the antiviral activity of the compounds obtained during successive synthetic steps revealed that some of them exhibited marked antiviral effect against toga, orthomixo, oncorna and herpes viruses.
