Abstract
本发明提供了一种全氟烷氧基化试剂及其制备方法和应用,具体地,本发明提供了一种如式A所示的全氟烷氧基化试剂,其可以用于本领域中常见的全氟烷氧基化反应,特别是三氟甲氧基化反应。本发明所涉及的全氟烷氧基化试剂原料廉价易得,反应条件温和,操作简单,成本低,容易推广,适合大批量生产。
Description
技术领域
本发明属于有机合成领域,具体地说,本发明涉及一种三氟甲氧基化试剂的制备方法及其用途,更具体地,涉及三氟甲氧基酯类化合物的制备方法,及其作为三氟甲氧基化试剂将三氟甲氧基团引入有机分子中的用途。
背景技术
在有机化合物中引入氟原子能够戏剧性地改变化合物分子的电子效应、立体效应以及脂溶性。人们发展了大量的方法和试剂,实现了诸多含氟化合物的合成。在所有被研究的含氟基团中,三氟甲氧基被称为“最不熟悉”的含氟基团,该基团的引入能够有效地提高分子的生物活性,但鲜有关于该基团引入的研究。
含三氟甲氧基的有机化合物在液晶材料、染色材料以及农药医药领域都有着重要的作用。现有技术中存在不少含三氟甲氧基的化合物,例如潜在的杀虫剂 Indoxacarb(茚虫威)、杀虫剂Triflumuron(杀铃脲)、生物生长调节剂Flurprimidol(呋嘧醇)、治疗肌肉萎缩药Riluzole(利鲁唑)(商品名:力如太)、杀菌剂Thifluzamide(噻呋酰胺)和钾管道的开放剂Celikalim等。然而,三氟甲氧基的引入是一件十分困难的事情,三氟甲氧基化试剂更是十分稀少。目前文献报道中有实用价值的只有以下种试剂,一是三氟甲磺酸三氟甲基酯(TFMT)可以释放三氟甲氧基负离子,实现诸如亲核取代反应等类型的反应,但该试剂为液体试剂,且沸点仅为19℃,操作使用不方便。二是苯磺酸三氟甲酯类试剂,可以实现对烯烃的不对称三氟甲氧基化溴化反应,但它是通过相应的苯磺酸与昂贵的togni试剂制备得到的,成本过于高昂。
综上所述,本领域迫切需要研发出更加廉价、易得的通用三氟甲氧基化试剂。
