Description
技术领域
本发明属于有机化合物合成及应用技术领域,具体涉及一种N-(2-芳基咪唑并[1,2-a]吡啶-3-基)双苯磺酰亚胺类化合物的制备方法。
背景技术
咪唑并吡啶是药物化学中常见的含氮杂环化合物(Comprehensive HeterocyclicChemistry III)。其衍生物具有很好的生物活性:例如,抗病毒、抗真菌、抗溃疡和抗菌性(Bioorg.Med.Chem.2015,23,6087;J.Med.Chem.2015,58,8529;Bioorg.J.Org.Chem.2012,77,5552;J.Med.Chem.2015,58,9238;Bioorg.Med.Chem.2011,19,4227;J.Med.Chem.1999,42,50)。目前有几类药已经成功上市,比如治疗失眠症的药物Zolpidem,治疗急性心衰的药物Olprinone,抗焦虑药物Alpidem和麻醉药Necopidem等(J.Med.Chem.2008,51,7243;Exp.Ther.2001,299,793;J.Behav.Pharmacol.1995,6,116)。近年来,咪唑并吡啶类化合物的官能团化反应的研究日趋成熟,但关于吡啶并咪唑的磺酰胺基化反应的研究却鲜有报道。
N-氟代双苯磺酰亚胺是有机合成中常用的氟化试剂和氨基化试剂(J.Am.Chem.Soc.2010,132,2856,Angew.Chem.Int.Ed.2012,51,1244,Green Chem.2017,19,1674),其可以很好的对有机分子进行修饰。该实验方法对于进一步研究N-氟代双苯磺酰亚胺的应用将有重要意义。
发明内容
本发明所要解决的技术问题是提供一种N-(2-芳基咪唑并[1,2-a]吡啶-3-基)双苯磺酰亚胺类化合物的合成及制备方法,该方法简单易行,成本低廉且易于纯化。

所述的N-(2-芳基咪唑并[1,2-a]吡啶-3-基)双苯磺酰亚胺类化合物的制备方法,包括下述步骤:在空气环境下,将2-芳基-咪唑并[1,2-a]吡啶类化合物与N-氟代双苯磺酰亚胺(NFSI)加入反应管中,加入四氟硼酸四乙腈铜(I),然后加入二氯乙烷,90~110℃下反应0.1~12小时;反应结束后色谱分离、干燥既得目标产物,反应方程式如下:
所述2-芳基-咪唑并[1,2-a]吡啶类化合物的通式为:
N-氟代双苯磺酰亚胺的结构式为:
其中R1为氢、烷基、烷氧基、腈基、酯基、卤素或三氟甲基;R2为氢、烷基、烷氧基、卤素、叔丁基或三氟甲基。
所述2-芳基-咪唑并[1,2-a]吡啶类化合物与N-氟代双苯磺酰亚胺的物质的量比为1:1~3。
所述四氟硼酸四乙腈铜(I)的用量为2-芳基-咪唑并[1,2-a]吡啶类化合物的物质的量0.1~1.2倍。
所述的二氯乙烷以0.2mmol 2-芳基-咪唑并[1,2-a]吡啶类化合物的物质的量为基准,所述溶剂的用量为1~2mL。
所述色谱分离采用的洗脱剂为体积比为0~100:100~0的乙酸乙酯和石油醚。
本发明的有益效果:本发明为合成N-(2-芳基咪唑并[1,2-a]吡啶-3-基)双苯磺酰亚胺类化合物提供了一种简便易行的方法。该反应利用廉价金属铜(I)作为促进剂,二氯乙烷作为反应溶剂,实现了咪唑并[1,2-a]吡啶化合物与N-氟代双苯磺酰亚胺的胺化反应。该方法简单高效,成本低廉且易于纯化,丰富了咪唑并[1,2-a]吡啶化合物的的官能团化反应类型。该方法将对咪唑并[1,2-a]吡啶化合物的胺化反应的研究和应用具有重要意义。
