Description
技术领域
本发明属于有机合成领域,具体涉及一种吲哚啉衍生物的合成方法。
背景技术
吲哚啉衍生物是医药和农药合成中常用的中间体,构成了一系列活性分子和天然产物的核心。因此,开发高效且简便的吲哚啉衍生物的构建方法是有机合成方法学中的一个重要分支题。如下式所示,2018年山东大学王瑶课题组通过热催化的方法使用三取代芳香胺与碘叶立德反应,成功构建了一系列的吲哚啉衍生物,然而该方案还需要使用到额外的氢化钙作为添加剂。因此,开发不需要使用额外催化剂以及添加剂的方法构建吲哚啉衍生物也同样具有一定的挑战性。
发明内容
本课题组通过研究发现,在蓝色LED灯照射下,三取代芳香胺与碘叶立德即可发生反应并且无需额外的催化剂以及添加剂,从而为吲哚啉衍生物的合成提供了温和的反应途径。同时我们也尝试了使用绿色LED灯作为光源,结果表明反应速率会急速下降。
基于以上研究背景,本发明提供了一种吲哚啉衍生物的合成方法,在可见光照射的条件下,利用三取代芳香胺与碘叶立德在1,2-二氯乙烷即可进行反应,简便的制备了各种吲哚啉衍生物。本方法不需要任何催化剂以及添加剂,只需要可见光作为绿色能源进行驱动。
本发明吲哚啉衍生物的合成方法,将三取代芳香胺1与碘叶立德2于溶剂1,2-二氯乙烷中,在光照条件下进行反应,分离提纯后得到目标吲哚啉衍生物。
合成路线如下所示:
三取代芳香胺1中的取代基R1为甲基、乙基、丙基、丁基、异丙基、氟、氯、溴或酯基。此外,氮上取代基可以为烷基或环烷基。
碘叶立德2中的取代基R2为甲基、乙基、异丙基或苄基。
所述分离提纯是通过硅胶柱层析分离纯化的方式,洗脱液为石油醚和乙酸乙酯,体积比20:1-5:1。
相较于现有技术,本发明的有益效果体现在:
1、所使用的原料容易制备,并且大多数三取代芳香胺可以商业购买。
2、无需使用任何催化剂以及添加剂,仅仅只需要普通蓝色LED灯进行光照。
3、反应条件温和,易于操作,并能通过流动光化学的方法进行大量合成。
