MICROWAVE ASSISTED SYNTHESIS OF BIOLOGICALLY ACTIVE 4-HYDROXY-7V-(PHENYLCARBONYL)-2H-1,2-BENZOTHIAZINE-3-CARBOHYDRAZIDE 1,1-DIOXIDE DERIVATIVES
Microwave assisted synthesis of a series of 4-hydroxy-N'-(phenylcarbonyl)-2H-1,2-benzothiazine-3-carbohydrazide 1,1-dioxides from sodium saccharin is reported. Sodium o-benzosulfimide was N-alkylated with ethyl chloroacetate followed by base catalyzed ring expansion to six membered 1,2-benzothi...
