3-(2,4-Dichlorophenoxy)-1-(4-methoxyphenyl)-4-(3-nitrophenyl)azetidin-2-one
In the title compound, C22H16Cl2N2O5, the nearly planar four-membered β-lactam ring [maximum deviations of 0.011 (2) for the N atom] makes dihedral angles of 68.34 (13), 83.04 (13) and 3.37 (13)° with the dichloro-, nitro- and methoxyphenyl rings, respectively. The crystal structure is stabilized by C—H⋯O hydrogen-bond interactions. In addition, a π–π stacking interaction [centroid–centroid distance = 3.6622 (12) Å] is observed between the β-lactam and nitrophenyl rings

Synthesis and biological evaluation of bile acid dimers linked with 1,2,3-triazole and bis-β-lactam
We report herein the synthesis and biological evaluation of bile acid dimers 11-18 linked through 1,2,3-triazole and bis-β-lactam. The dimers 11-18 were synthesized using 1,3-dipolar cycloaddition reaction of diazido bis-β-lactams 3, 4 and terminal alkynes 7-10 derived from cholic acid/deoxycholic acid in the presence of Cu(I) catalyst (click chemistry). These novel molecules were evaluated in vitro for their antifungal and antibacterial activity. Most of the compounds exhibited significant antifungal as well as antibacterial activity against all the tested fungal and bacterial strains. Moreover, their in vitro cytotoxicities towards HEK-293 and MCF-7cells were also established
