Description
技术领域
本发明涉及一种β,δ-位不同官能团取代的芳香酮类化合物的制备方法。
背景技术
酮类化合物是一类分子内拥有羰基官能团的化合物,因为羰基较高的反应活性,可以进行许多转化(比如亲核反应、缩合反应等),使得酮类化合物在有机合成领域具有非常重要的地位。分子内含有不同官能团取代的酮类化合物,则反应位点更丰富多样,能发生分子内或分子间的反应,合成许多具有生物活性的分子。常见的1,5-二羰基化合物可以在不同的反应条件下关环合成不同种类的杂环化合物。比如可以合成多取代的吡啶环(Synthesis 2006,10,1664.)、可以自身发生McMurry偶联反应形成环戊二烯化合物(J.Org.Chem.2006,71,9873.)、也可以关环合成含有不同取代基的杂环化合物(Heterocycl.Commun.2003,9,599.)。传统的合成1,5-二羰基化合物的方法主要是通过Michael加成反应合成,但对于有其它吸电子取代基的底物则存在选择性较差等缺点。综上所述,开发含有不同官能团取代的酮类化合物具有非常重要的意义。

该方法的反应通式如下:
催化剂可以是下述化合物中的任意一种:氯化亚铁、乙酰丙酮亚铁、乙酰丙酮镍、硫酸镍、双水杨酰胺乙基钴。溶剂为下述化合物的任意一种:乙腈、乙酸乙酯、1,2-二氯乙烷、氯苯、氟苯、三氟甲苯。氧化剂为:有机相的叔丁基过氧化氢、水相的叔丁基过氧化氢。碱为下述化合物的任意一种:1,4-二氮杂二环[2.2.2]辛烷、1,8-二氮杂二环十一碳-7-烯、三乙胺、叔丁醇钠、氢氧化钠、醋酸钠、碳酸铯、4-二甲氨基吡啶。上述催化剂的用量为式III结构通式所示化合物的摩尔用量的0.01%-150%,氧化剂的用量为式III结构通式所示化合物的摩尔用量的50%-500%,碱的用量为式III结构通式所示化合物的摩尔用量的10%-300%。另外,该反应的反应温度为20-150℃,反应时间为0.1-72小时。
本发明通过一次反应实现两个烯烃的双官能团化反应和交叉偶联,构筑3个新的化学键和引入两个新的功能团芳香酮产物中;本发明所使用的原料与催化剂价廉易得、操作简单方便;反应条件温和,对光、空气、水分均不敏感,产率较高,产物易分离纯化,有很好的应用前景。
