Synthesis and antimicrobial activity of Phthalimide derivatives

A series of novel phthalimide derivatives (SV 1-8) have been synthesized and evaluated for antimicrobial activity. The target compounds were prepared by fusion of glycine with phthalic anhydride at 150-155 ºC to afford 2-(1, 3- dioxoisoindolin-2-yl) acetic acid. The compound 2-(1, 3-dioxoisoindolin-2-yl) acetic acid was treated with thionyl chloride in chloroform to afford 2-(1, 3-dioxoisoindolin-2-yl) acetyl chloride which was further treated with substituted phenols in presence of anhydrous potassium carbonate in dry acetone yielded the final compounds (SV1-8). The structures of the target compounds were characterized on the basis of their m.p., TLC, IR and 1H-NMR data. All the target compounds were evaluated for antibacterial and antifungal activity.
