Description

一种多取代吡喃并[3,2-b]吡喃衍生物的合成方法
技术领域
本发明属于有机合成技术领域,涉及2-氨基-4,8-二氢-6-甲基-8-氧代-4-苯基吡喃并[3,2-b]吡喃衍生物的有机合成方法。 
背景技术
吡喃及其衍生物具有广泛的生物活性和药理活性,例如抗菌活性,抗骨质疏松活性,抗氧化活性,温和的麻醉活性,抗高血压活性,抗凝固活性,抗真菌活性,抗肺结核活性,抗过敏和抗癌等活性。因此吡喃衍生物一直是化学工作者和药物科学工作者关注的一个热点。但对于吡喃并[3,2-b]吡喃衍生物的合成报道很少。2007年有人报道通过重排反应制备吡喃并吡喃化合物(Niethe,A.Heterocycles 2007,74:803-817),2010年Chakraborty等报道利用烯糖衍生物与各种酚化合物在三氯化铟催化下合成手性吡喃并吡喃化合物(Soumik Roy Tetrahedron 2010,66:8512-8521),Anary-Abbasinejad等则通过4-羟基香豆素或4-羟基-6-甲基吡喃酮与乙炔的二羧酸酯反应构建吡喃并吡喃骨架(Anary-Abbasinejad,M.J.Braz.Chem.Soc.2010,21:319-U212)。但在离子液体中通过醛、5-羟基-2-甲基-4H-吡喃-4-酮和活泼亚甲基化合物为原料合成该类化合物还未见报道。 
发明内容
本发明的目的在于提供一种合成2-氨基-4,8-二氢-6-甲基-8-氧代-4-苯基吡喃并[3,2-b]吡喃衍生物的方法:醛、5-羟基-2-甲基-4H-吡喃-4-酮和活泼亚甲基化合物为原料,按摩尔比1∶1∶1在离子液体中经三组分一锅法一步反应生成(如图1所示)。本发明在合成吡喃并[3,2-b]吡喃衍生物过程中引入离子液体,提供一种温和高效,环境友好,应用范围广,产率高且离子液体可循环使用的合成方法。 
本发明通过下述方法实现的:在5毫升离子液体中加入1毫摩尔的醛,1毫摩尔的5-羟基-2-甲基-4H-吡喃-4-酮和1毫摩尔的活泼亚甲基化合物,在80℃下反应3-20小时,即得到相应的2-氨基-4,8-二氢-6-甲基-8-氧代-4-苯基吡喃并[3,2-b]吡喃衍生物。 
所述的离子液体为[Bmim]Br或[Bmim]BF4
所述的醛为芳香醛、脂肪醛或杂环醛。 
所述的活泼亚甲基化合物为为丙二腈、氰乙酸酯、氰乙酰胺。 
所述的离子液体制备参见文献(Park,S.J.Org.Chem.2001,66:8395-8401)。 
与文献中已有方法相比,本发明具有以下优点: 
本发明在合成吡喃并[3,2-b]吡喃衍生物的过程中引入离子液体,是一种绿色合成方法。离子液体具有蒸汽压低,毒性小、热稳定性好、不燃烧和不爆炸、溶解性能独特,反应产物分离简单等优点。且离子液体可循环使用,大大降低了成本。
