Description
技术领域
本发明属于有机合成技术领域,特别涉及一种多取代的2H-噻吩并[2,3-b]吲哚衍生物的制备方法。
背景技术
噻吩并吲哚类衍生物是一类常见的具有生物活性和药理活性广泛存在于天然产物中的杂环化合物。很多噻吩并吲哚类衍生物具有杀菌、抗高血压、抗抑郁、抗过敏、抗疟疾、抗肿瘤等生物活性和药理活性,如2H-噻吩并[2,3-b]吲哚衍生物可进一步转化生成一种控制稻秧活性的化合物。
噻吩并吲哚类衍生物的合成应用已经超出医药领域,逐渐延伸至材料化学领域,如噻吩并吲哚衍生物电化学共聚制备高性能导电聚合物和有机电致发光器件等。
噻吩并吲哚衍生物在这些领域具有广泛用途,使得这些化合物的合成具有特别重要的意义。
噻吩并吲哚衍生物的制备方法有:
1)PeterLanger合成法:3-卤代色原酮、β-酮酰胺和1,3-二氢吲哚-2-硫酮反应,得到噻吩并吲哚衍生物。
2)TakashiOtani合成法:2-烷基苯基异硫氰酸酯在三氟甲磺酸催化下成环,得到噻吩并吲哚衍生物。
3)TakaoSaito合成法:邻炔基异硫氰酸酯在羰基钴或羰基钼的催化下,通过Pauson-Khand反应得到噻吩并吲哚类衍生物。
利用上述方法在实验室中制备噻吩并吲哚衍生物,具有明显的缺点:1)合成步骤多、操作繁琐、催化金属昂贵。2)反应在强酸或强碱性条件下进行,对环境污染大;3)部分试剂毒性大,反应条件苛刻。
发明内容
为了克服上述现有技术的不足,本发明提供了一种多取代噻吩并吲哚衍生物及其制备方法。
一种多取代噻吩并吲哚衍生物,具有式Ⅰ所示结构:
式Ⅰ中,其中R1选自环己基、正丁基、叔丁基、2,6-二甲基苯基;R2选自氟原子、氯原子、溴原子、饱和三元环、叔丁基、噻吩基、苯基、取代芳基,其中的取代基团为氟原子、氯原子、甲基、甲氧基;R3选自氢原子、氟原子、氯原子、甲基、甲氧基;R4选自氢原子、氟原子、氯原子、甲基。
由邻炔基异硫氰酸酯和异腈,在镍催化下,溶剂中加热反应完毕后得到一种多取代噻吩并吲哚衍生物;该制备方法用以下方程式II表示:
选用的镍催化剂为乙酰丙酮镍,乙酰丙酮镍的用量为邻炔基异硫氰酸酯物质的量的0.3%,邻炔基异硫氰酸酯和异腈的摩尔比值为1.0:1.2,选用的溶剂是四氢呋喃,反应温度为80℃,反应时间为5h。
本发明的有益效果为:本发明提供的多取代噻吩并吲哚衍生物的合成方法科学合理,可以合成得到具有各种取代基的2H-噻吩并[2,3-b]吲哚衍生物;并且还具有合成方法简单,产率较高、产品易于纯化等特点。
