The structure of the new derivatives was confirmed by the spectral data and elemental analyses. Out of five new derivatives, three were revealed mild to moderate activity compared with Streptomycin & Fluconazole as a reference standard. Among this new series, 3-chloro-1-(4-fluoro phenyl)/(4-chloro phe-nyl)-4-(pyridine-3-yl) azetidine-2-one (4a & b) were found most activity.展开更多
