摘要:本文根据已有的利奈唑胺衍生物的合成研究以及构效关系方面的讨论总结,设计合成了一个新的含三氟甲基的噁唑烷酮类化合物。合成路线为以简单的烯醚,环氧氯丙烷以及含氟酸酐为原料,通过多步反应合成了一个结构新颖的噁唑烷酮杂环化合物。具体为利用中间体1-(4-硝基-苯基)-5-三氟甲基-1H-吡唑经还原,CBZ-Cl酰化得中间体9a,(s)-环氧氯丙烷经氨化成盐,双乙酰化得(s)-N-[2-乙酰氧基-3-氯丙基]乙酰胺3a。采用汇聚合成方法,将中间体9a与双乙酰化合物3a拼接,再通过多步反应合成目标化合物。29952 毕业论文关键词:噁唑烷酮;抗菌药;利奈唑胺衍生物;三氟甲基
The Synthesis of Linezolid Derivatives containing the trifluoromethyl group
Abstract:This article gives linezolid derivatives research and structure-actitivity relationships, and the design of a new fluorine-containing oxazolidinone compounds. With a simple enol ethers, epichlorohydrin and fluorine-containing acid anhydride as raw material, through a short series of oxazolidinone was synthesized heterocyclic compounds. For concrete, using the intermediate 1-(4-nitro-phenyl)-5- (trifluoromethyl)-1H-pyrazole. After reduction, CBZ-Cl was acylated intermediate 9a. (s) - epichlorohydrin by ammoniation a salt of too diacetyl (s)-N-[2-acetoxy- 3- chloropropyl]-acetamide 3a. Synthesis method using the aggregation of the intermediate 9a and the compound 3a by one step synthesis of diacetyl compound.
