series of novel 12-alkoxyiminothiopentadecanlactones were synthesized starting from 2-nitrocyclododecanone by Michael addition to acrolein, followed by selective reduction of the aldehyde group, conversion of hydroxyl group to mercapto group, ringexpansion, Nef reaction, and finally reaction with alkoxyamines. Their structures were confirmed by 1H NMR, 13C NMR spectra, and mass spectrometry. The Z and E

cycloaddition of aza‐oxyallylic cations with ethynylbenziodoxolones for synthesis of new λ3‐iodanes containing spirocyclic 4‐oxazolidinone has been developed. This cyclic λ3‐iodanes display stability in air and excellent solubility in organic solvent. Using them as substrate, both the 4,1‐benzoxazepine‐2,5‐diones and symmetrical 1,3‐diynes derivatives were afforded in high yield under copper(I)‐catalyzed

Quinolone are a class of potent broad-spectrum antibacterial drugs that target the bacterial type II DNA topoisomerases (DNA gyrase) and topoisomerase IV. In the present study, the synthesis and evaluation of cytotoxicity activity of a new series ofN-pipearzinyl quinolones containingN-2-(furyl-2-yl)-2-(chlorobenzyloxyimino) ethyl moiety(6a-c)have been studied. Preliminary screening showed that one of the new compounds, namely 7-(4-(2-(3-chlorobenzyloxyimino)-2-(furan-2-yl) ethyl) piperazin-1-yl)-1-cyclopropyl-6-fluoro-4-oxo-1, 4-dihydroquinoline-3-carboxylic acid(6b)showed significant cytotoxic activity against human breast tumor cell lines.
