摘要
目的对嗯唑烷酮类化合物5-位侧链进行结构修饰与改造,并初步评价其体外抗菌活性。方法以间氟苯胺为原料,经9~12步反应合成目标化合物;采用二倍稀释法,测定目标化合物的体外抗菌活性。结果设计、合成了30个新化合物,其中目标化合物18个,其结构经^1H NMR及MS等方法确证,11个化合物显示出不同程度的抗菌活性,化合物7a,9a和11a的活性较好。结论化合物7a,9a和11a值得进一步研究。
Aim To modify the C-5 side chains vitro antibacterial activities preliminarily. Methods of the oxazolidinone derivatives and evaluate their in The title compounds were synthesized in 9 - 12 steps with the starting material 3-fluoroaniline and their in vitro antibacterial activities were examined by using Mueller-Hinton broth dilution method. Results Thirty new compounds were designed and synthesized, in which eighteen novel title compounds were prepared and their structures were confirmed by ^1H NMR and ESI-MS. Eleven compounds showed antibacterial activities to a certain extent, among them compounds 7a, 9a and lla displayed promising activity. Conclusion Compounds 7a, 9a and lla were worth further studying.
