Description
(一)技术领域
本发明涉及一种铱光催化合成9-乙酰氧基-9,10-二氢菲类化合物的方法。
(二)背景技术
二氢菲类化合物又名9,10-二氢菲类化合物,其广泛存在于自然界,在很多中草药中都能发现此类化合物的踪迹。由于其结构的特殊性,使其在工业上有独特的应用价值,同时二氢菲类化合物作为一种重要的医药中间体,可以有效的抑制炎症因子的产生,可以合成一系列抗癌药物,是很多抗癌药物的主体框架。除此之外,取代类的二氢菲具有一个或者两个手性中心,可以设计合成一系列手性配体。例如2002年,曾等人报道了一系列衍生自9,10-二氢菲-9,10-二醇的手性配体的设计、合成以及在不对称催化方面的应用(Chin.J.Synth.Chem.,2002,10,95-97),由此可见二氢菲类化合物在手性配体方面也有着很大的应用前景。而本发明所报道的9-乙酰氧基-9,10-二氢菲可以进一步氧化得到9-乙酰氧基菲类化合物,而菲类化合本身也是一种重要的医药中间体和化工原料。进一步,9-乙酰氧基-9,10-二氢菲可以通过水解的方式得到9-羟基-9,10-二氢菲,此类化合物带有一个手性中心,可以在手性配体方面得到相应的应用(scheme 1)。
随着近些年对于光催化的研究深入,越来越多的光敏剂得到了开发,并投入到了我们的生产生活当中,其中应用最为广的当属贵金属铱相对应的金属配合物了,目前合成二氢菲类化合物的方法比较多,例如2011年,Daniela等人报道(Org.Lett.,2011,13,12)以2-苯乙基碘苯为底物,叔丁醇钾作为碱,吡啶作为溶剂,在160℃高温条件下,采用自由基加成环化的方式,合成了二氢菲类化合物,但这种合成的方式有着较大的局限性,需要在高温条件下进行,与此同时,采用吡啶这种毒性较大的溶剂,对环境影响较大,不利于工业化生产。对于二氢菲类化合物的合成报道相对比较多了,但是合成9号位取代二氢菲类化合物相关文献报道就明显少了很多,而传统合成9-乙酰氧基-9,10-二氢菲一般采用9-羟基-9,10-二氢菲与乙酸酐为底物,吡啶作为溶剂,加热反应生成,同样这种方法采用了不友好溶剂吡啶,同时需要提前先制备9-羟基-9,10-二氢菲,原料相对不是那么易得。因此寻求一种更加环保,更加贴近绿色化学时代主题的方法是很有必要的。
随着近些年对于光催化的研究深入,越来越多的光敏剂得到了开发,并应用于我们的生产生活当中,其中应用最为广泛的当属贵金属Ir相对应的金属配合物了,经过各个方面的研究测试表明,该光敏剂有着较高的催化活性,较长的激发态保留时间。而本发明结合了铱光敏剂的高反应活性,以一个相对较为容易合成的2-苯基-α-乙酰氧基-苯乙烯类化合物作为底物,相对毒性较小的四氢呋喃为溶剂,常用的K2CO3为碱,在室温条件下,以较高的收率获得目标产物9-乙酰氧基-9,10-二氢菲类化合物。此方法,不需要额外进行加热,能耗低,操作简单,100%原子利用率,符合当今绿色化学发展的时代主题。
