Description
技术领域
本发明属于精细化学品及相关化学技术领域，提供了一种高效的多取代丙烯基芳香化合物的制备方法。
背景技术
丙烯基芳香化合物广泛存在于天然产物、医药和农药中间体中。此外，丙烯基中的甲基以及碳碳双键部分也易于进行官能化，为其进一步修饰提供了可能。因此，开发一种简便有效的合成方法，来得到多取代的丙烯基芳香化合物越来越受到人们重视。
传统的多取代丙烯基芳香化合物的合成方法主要是在化合物的原有结构基础上进行化学修饰。除了常见的芳香卤化物与丙烯基硼酸频哪醇酯的Suzuki-Miyaura偶联反应外(Tetrahedron Lett.,2008,49,5605-5607)，还包括芳香炔烃的半还原(J.Am.Chem.Soc.,2016,138,8588-94)、苯甲醛与乙基三苯基溴化鏻的Wittig反应(J.Org.Chem.,2008,73,801-812)、芳香醇的脱水(Eur.J.Org.Chem.,2008,2008,5577-5582)、烯丙基苯的双键异构化(Org.Lett.,2012,14,3716-3719)等一系列将丙烯基引入芳香化合物的方法。然而，这些方法受到官能团兼容性差、需要进行预官能化以及苛刻的反应条件的限制。
相比之下，由过渡金属催化的直接C-H丙烯基化反应是一种更理想的方法。到目前为止，共有两种类型的底物可用于直接C-H丙烯基化反应。一种是含有导向基团的芳香化合物(Adv.Synth.Catal.,2016,358,3932-3937)，另一种是含有多个吸电子基团的芳香化合物(Angew.Chem.Int.Ed.,2016,55,1876-1880)。然而，这些方法有时会得到烯丙基产物和丙烯基产物的混合物，而且大多需要在高温(超过100℃)下生成。
因此，为了得到种类更丰富的多取代丙烯基芳香化合物，需要开发一种底物适用性广、反应条件温和、官能团相容性良好和高区域选择性的合成方法。
发明内容
本发明提供了一种多取代丙烯基芳香化合物的新颖制备方法，该合成方法为一锅法，反应条件温和、操作简便、收率高、区域选择性好。

分离方法为柱层析。
用柱层析方法进行产物分离时，可以使用硅胶或者中性氧化铝作为固定相，展开剂一般为极性与非极性的混合溶剂，如乙酸乙酯-石油醚、乙酸乙酯-正己烷、二氯甲烷-石油醚、甲醇-石油醚。
本发明的有益效果是该合成方法为一锅法、反应条件温和、操作简便、收率和区域选择性高；利用该方法所合成的多取代丙烯基芳香化合物可以进一步官能化得到各类化合物，应用于天然产物、功能材料及精细化学品的开发与研究。
