摘 要:以2,4-二甲氧基苯胺为原料,经酰胺化、傅克酰基化、肟化、环合及水解5步反应,合成了新骨架3-乙基-6-甲氧基苯并[d]异噁唑-5-胺(1)。对关键步骤的反应机理进行分析,筛选合成方法,优化后处理操作工艺。该方法原料易得,操作简单,且收率较高。目标化合物经1H NMR、13C NMR、 MS和IR确证。此外,分子对接及类药性计算表明,化合物1可有效结合到BRD4溴结构域口袋,也具有良好的类药性。The novel scaffold of 3-ethyl-6-methoxybenzo[d]isoxazole-5-amine(1) was synthesized in five steps including amidation, Friedel-Crafts acylation, oximation, cyclization and hydrolyzation using 2,4-dimethoxyaniline as the starting material. The reaction mechanism of the key step was analyzed, the synthetic method was screened and the post-processing operation was optimized. The method had the advantages of easy availability of raw materials,simple operation and high yield. The target compound was confirmed by1 H NMR,13 C NMR, MS and IR. In addition,molecular docking and drug-like calculations showed that compound 1 could effectively bind to the BRD4 bromodomain pocket and possessed good drug-like properties.
