Facile and green syntheses of novel 2-(1,2-benzisothiazole-3-one-1,1-dioxide)-N-arylacetamides, 2-(1,3-
dioxoisoindolin-2-yl)-N-arylacetamides and 2-(N-(2-oxo-2-(arylamino)ethyl)sulfamoyl (or) carbamoyl)benzoic acids have
been developed and tested for their biological activities against Baccilus megaterieum, Escherichia coli, Providencia
stuartii, Pseudomonas putida. Some of the synthesized compounds possess good activity against Escherichia coli and
Baccilus megaterieum compared to standard drugs.
