Description
技术领域
本发明属于催化合成技术领域,涉及一种含硼吲哚啉酮衍生物的制备方法,更具体地说,涉及一种通过铜催化邻碘苯胺衍生物与联硼酸频那醇酯的环化反应合成含硼吲哚啉酮衍生物的方法。
背景技术
杂环化合物普遍存在于天然产物和生物活性分子中,并在医药、农药、染料、生物等领域受到广泛关注。作为一类重要的杂环分子,吲哚啉酮化合物一直是有机合成化学家们的研究对象之一。近年来,利用不同的反应策略,吲哚啉酮的合成研究已经有了较多的文献报道。其中,基于钯催化串联环化反应策略,通过邻碘苯胺衍生物经由生成的烷基钯中间体与不同试剂的偶联反应,是实现含季碳中心吲哚啉酮化合物合成最直接的方法之一。所涉及的偶联试剂,如联硼酸频那醇酯(Chem.Commun.2015,51,14862-14865)、偶联试剂为氰化物(Chem.Eur.J.2007,13,961-967)、偶联试剂为炔烃的钯催化的Heck-Sonogashira串联反应(Chem.Eur.J.2014,20,1843-1846)均已报道。然而,这些反应均局限于价格较为昂贵的金属钯为催化剂,因此发展廉价金属盐作为催化剂来实现吲哚啉酮衍生物的构建是具有重要研究意义。
Van der Eycken,Chem.Commun.2015,51,14862-14865.
其中,邻碘苯胺衍生物能以易得的N-甲基邻碘芳胺与阿托酸酰氯为原料,在三乙胺的作用下方便制取(Angew.Chem.Int.Ed.2013,52,12385-12389.)。
