Description
本申请为申请号为2017113298008、申请日为2017年12月13日、发明名称为“一种钌催化芳香酮与二苯乙炔环化反应制备多芳取代萘衍生物的方法及应用”的分案申请。
技术领域
本发明涉及医药技术及光电材料领域,主要涉及多芳取代萘衍生物的制备方法及应用。
背景技术
多芳取代萘衍生物由于其独特的电化学,光化学性能以及它们在n共轭的功能材料上的应用,使其在有机荧光材料、半导体材料等方面的应用越来越广泛,并且多芳取代萘衍生物在药物合成方面也有重要应用。现有技术中已采用的制备方法相比以前的环金属化、芳基卤、芳基酸等比较苛刻的条件有了很大的突破。目前,多采用在温和条件下通过过渡金属催化芳香苯环的C-H键(甚至双C-H键)活化与炔烃发生环化反应制备多芳取代的萘衍生物。但该方法存在缺陷,这些反应需要一定量的配体或者当量的金属盐做氧化剂才能完成催化循环,不仅提高了生产成本,而且金属盐多为对环境污染的重金属(铜、银等)盐类。基于此,本领域需要更加环保、绿色、经济的方法来合成多芳取代萘衍生物。
发明内容
为弥补现有技术的不足,本发明提供了一种无需添加剂及氧化剂在温和条件下以较廉价的钌([RuCl2(p-cymene)]2)作为催化剂合成了多芳取代萘的衍生物的方法。
本发明采用如下技术方案:多芳取代萘的衍生物,具有如通式Ⅰ所示的结构:
本发明另一个目的是请求保护上述多芳取代萘的衍生物的制备方法,即:将二苯乙炔与芳香酮作为原料,加入[RuCl2(p-cymene)]2、碱和非极性有机溶剂,在氮气环境下加热至80-100℃反应12-24h,经柱层析分离得到多芳取代萘的衍生物;所述的二苯乙炔与芳香酮摩尔比为1:2,[RuCl2(p-cymene)]2占二苯乙炔的15mol%,碱与芳香酮的摩尔比为1:1。
进一步的,所述非极性有机溶剂为苯、甲苯、二氯乙烷、氯仿、苯乙烯、环乙烷或己烷中任一种。优选甲苯。
进一步的,所述的碱为KOAc、Na2CO3、Cs2CO3、K2CO3、Li2CO3、NaOAc、LiOAc中的一种或一种以上。优选KOAc和Na2CO3。
作为本发明优选的实施方案,该多芳取代萘衍生物的制备方法为:将芳香酮和二苯乙炔置于封管中,加入[RuCl2(p-cymene)]2和甲苯,同时加入干燥的碳酸钠和醋酸钾在氮气环境下加热至100℃反应24小时,经柱层析分离得到多芳取代萘的衍生物。
本发明第三个目的是请求保护上述多芳取代萘的衍生物在药物制备及光电材料领域上的应用。
与现有技术相比,本发明的有益效果是:
本发明使用较廉价的钌([RuCl2(p-cymene)]2)作为催化剂,将芳香酮β-H活化合成六元环即生成多芳取代萘衍生物;反应过程中无需添加剂及氧化剂,仅使用简单的碱,在温和反应条件下进行。本发明提供的合成方法简单易行、科学合理、绿色环保、经济实用,适合规模化生产。

表1
*催化剂为0.015mmol时的产率
由表1数据和对实施例1-6产率对比可知,当有机溶剂选择甲苯,碱为碳酸钠和醋酸钾时,催化剂用量为15mol%时,产率最高。故而,在实验过程中均采用此最佳反应条件进行。
