Description
技术领域
本发明涉及有机合成领域,具体地涉及一种α-重氮鎓盐化合物的制备方法和在合成多取代呋喃化合物中的应用。
背景技术
呋喃化合物广泛存在于天然产物和药物分子中,同时也是重要的有机合成反应砌块和构建高分子材料的基础骨架。近年来,利用重氮化合物与炔烃反应一直是合成多取代呋喃化合物的有效手段。但在现有已报道的合成方法中有以下局限性:1)利用重氮化合物与炔烃制备呋喃的反应,其所用底物炔烃往往为末端炔烃,以内炔为底物与重氮化合物反应制备呋喃仅有两例报道(M.G.Coleman.Org.Biomol.Chem.,2012,10,7483;O.P.Strausz.J.Org.Chem.,1987,52,2680),因此缺乏利用重氮化合物与炔烃反应制备全取代呋喃的通用手段。2)利用重氮化合物与炔烃反应制备呋喃,往往需要使用昂贵的过渡金属催化剂参与催化反应,实验条件复杂,存在金属残留的问题,这限制了其在工业生产中的应用。
发明内容
为解决上述问题,本发明公开了一种α-重氮鎓盐化合物的制备方法和在合成多取代呋喃化合物中的应用。
一种α-重氮鎓盐化合物,所述化合物的分子通式如下所示:
其中Y包括硫醚、硒醚、碲醚、胺、膦或胂。硫醚、硒醚、碲醚、胺、膦或胂的取代基包括C1~C20的烃基、苯基、取代苯基、1-萘基、2-萘基、杂芳基或苄基;EWG是吸电子取代基;X为抗衡阴离子。
一种α-重氮鎓盐化合物的合成方法,包括以下步骤:S10:将重氮化试剂加入至溶有酰氯的干燥的有机溶剂中,反应得到第一化合物;S20:将三氟甲磺酸根源加入至三价碘的干燥有机溶剂中,之后加入所述第一化合物,反应得到第二化合物;S30:将化合物Y加入所述第二化合物的有机溶剂中,反应得到第三化合物;S40:在有机溶剂中将所述第三化合物与对应的NaX进行抗衡阴离子交换得到所述α-重氮鎓盐化合物,所述α-重氮鎓盐化合物的分子通式如下所示:
其中Y包括硫醚、硒醚、碲醚、胺、膦或胂。硫醚、硒醚、碲醚、胺、膦或胂的取代基包括C1~C20的烃基、苯基、取代苯基、1-萘基、2-萘基、杂芳基或苄基;EWG是吸电子取代基;X为抗衡阴离子。
一种利用所述α-重氮鎓盐化合物合成多取代呋喃化合物的方法。
本发明提供的α-重氮鎓盐化合物含有多个官能团,结构可控,可直接用于高效率地合成多取代呋喃化合物。值得注意的是,EWG是吸电子取代基,若替换为给电子取代基(如烷氧基)或电中性取代基(如氢、苯基),则无法得到多取代呋喃化合物。
