技术领域
本发明属于有机化合物领域,具体涉及异喹啉酮类化合物及其合成方法。
背景技术
异喹啉酮类化合物以其独特的化学结构和丰富的药理活性在异喹啉类衍生物中占据重要地位。研究发现:多种天然活性化合物或药物活性中间体内都具有异喹啉酮母核结构,如异喹诺酮类化合物和上市药物格列喹酮,这些结构既独特又多样化的化合物具有抗肿瘤、抗病毒、抗菌等多种多样的生物和药物活性。
异喹啉酮类化合物作为一种重要的药物先导化合物,其合成方法及合成新的该类化合物广受关注。现有合成异喹啉酮类化合物的方法分为光催化、金属催化、非金属催化、电化学催化四大板块。这些方法大多是以N-烯丙酰基苯甲酰胺及其衍生物为底物经分子内环化反应得到相应的含有异喹啉酮类母体结构单元的产物。这类关环反应大多需要使用贵金属或重金属催化,存在着高成本或污染环境等局限性。因此,需要探索出更经济便捷、对环境更友好的高效合成方法。
发明内容

为实现上述发明目的,本发明所采用的技术方案是:一种合成异喹啉酮类化合物的方法,以高价碘化合物为氧化剂,以异喹啉或异喹啉的衍生物为底物,加入溴化苄或溴化苄的衍生物或溴丙烯后进行反应;所述异喹啉的衍生物指异喹啉苯环上存在取代基的化合物。
优选的,所述高价碘化合物为三价碘化合物或五价碘化合物。
优选的,在溶剂中依次加入异喹啉或异喹啉的衍生物、溴化苄或溴化苄的衍生物或溴丙烯、高价碘化合物,搅拌反应一段时间。
优选的,所述高价碘化合物为三价碘化合物,所述溶剂为二甲基甲酰胺、乙腈中的任意一种。
优选的,所述三价碘化合物为二乙酰氧碘苯。
优选的,所述反应温度为25~50℃。
优选的,所述高价碘化合物为五价碘化合物时,所述溶剂为N-甲基吡咯烷酮、乙腈中的任意一种。
优选的,所述五价碘化合物为戴斯-马丁高碘烷、2-碘酰苯甲酸中的任意一种。
优选的,所述反应温度为0~25℃。
相应的,利用所述方法制备获得的化合物,所述化合物的结构式为:
本发明具有以下有益效果:本发明提供了一种以异喹啉为底物,经高价碘尤其是戴斯马丁试剂氧化直接反应合成了异喹啉酮类化合物(异喹啉-1,3-二酮和异喹啉-1,3,4-三酮衍生物)的方法,并根据该方法合成了22种全新的化合物。与此类化合物传统的合成方法相比,本发明提供的方法底物价格低廉、易于获取、反应条件温和,是一种环境友好的、高效的合成方法。
具体实施方式
本发明提供了一种异喹啉酮类化合物的合成方法,具体包括如下步骤:在溶剂中依次加入异喹啉或其衍生物(以下统称“异喹啉”)、溴化苄或其衍生物(以下统称“溴化苄”)或溴丙烯、高价碘试剂,搅拌反应一段时间。反应结束后,用饱和食盐水和乙酸乙酯进行萃取,并将有机相减压旋干,有机相通过柱层析色谱法以石油醚:乙酸乙酯为洗脱剂分离,得到目标化合物。所述高价碘试剂为三价碘试剂或五价碘试剂,优选为五价碘试剂。具体反应方程式如下。
其中,1a为异喹啉,2a为溴化苄,A为选择三价碘试剂时生成的异喹啉酮类化合物,1b为选择五价碘试剂时生成的异喹啉酮类化合物。该反应方程式只体现了反应底物为异喹啉和溴化苄的情况,未体现衍生物、溴丙烯的情况。
需要说明的是:溴化苄衍生物指溴化苄的苯环上存在取代基的化合物,其结构式为:R1为在苯环间位或对位的-NO2、-Br、-Cl、 -CH3、-OCH3,异喹啉衍生物仅指异喹啉的苯环上含有取代基的衍生物,不包括异喹啉含氮杂环上含有取代基的衍生物,其结构式为:R2为-Br、-Cl、-CH3、OCH3。
优选的方案为:当高价碘为三价碘试剂时,所述溶剂优选为DMF(二甲基甲酰胺)、MeCN(乙腈)、中的任意一种,三价碘试剂优选为PIDA (二乙酰氧碘苯)。
优选的方案为:当高价碘为五价碘试剂时,所述溶剂为NMP(N-甲基吡咯烷酮)、DMF、MeCN中的任意一种,五价碘试剂优选为DMP(戴斯 -马丁高碘烷,又称戴斯马丁试剂)、IBX(2-碘酰苯甲酸)中的任意一种。
反应温度可选为25℃。优选的方案为:当高价碘为三价碘试剂时,反应温度为25~50℃,更优选为25℃;当高价碘为五价碘试剂时,反应温度优选为0~25℃,更优选为0℃。
更优选的方案为:以NMP为溶剂,以DMP为高价碘试剂,按当量比,异喹啉:溴化苄:DMP=1:2:2.4,在0℃下反应24~36h。
更优选的方案为:所述反应体系中含有一定量的水,按当量比,异喹啉:水=1:2~8,优选为1:4。本方法使用常规分析纯的95%N-甲基吡咯烷酮(NMP)溶剂,水无需额外添加到反应体系中。
更优选的方案为:以95%NMP为溶剂,以DMP为高价碘试剂,按当量比,异喹啉:溴化苄:DMP=1:2:2.4,在0℃下反应36h。
下面将对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅是本发明一部分实施例,而不是全部的实施例。若未特别指明,实施例中所用的技术手段为本领域技术人员所熟知的常规手段。所获得的数据均为进行至少3次重复后获得的平均值,且各重复获得的均为有效数据。发明人课题组前期试验中发现:异喹啉与氯化苄或甲苯在高价碘条件下都不发生反应,仅和溴化苄、溴丙烯发生反应。其中,与溴化苄反应时产物的收率更高,故后续实施例均以溴化苄为反应底物进行。

结果显示:不管是三价碘试剂还是五价碘试剂催化的异喹啉氧化反应,相同条件下,反应温度越高,其薄层色谱点板观察到的点越杂,反应效果越差。当反应条件为冰浴时,三价碘条件下的反应体系不发生反应,但五价碘试剂催化的反应在冰浴条件下反应主产物的产率却有所提高,当温度降到-10℃时,均不发生反应。且明显五价碘试剂的效果优于三价碘实际,因此后续实施例中均以五价碘试剂为基础进行实验。
