本发明公开了一种具有多官能团化的环己烷化合物及其制备方法,属于有机化学合成方法技术领域,该化合物以双亲核试剂丙二腈和两分子α,β‑不饱和酮为原料,以碱性物质为催化剂,在溶剂中于0‑50℃的温度下反应1‑48h,然后通过柱层析纯化,制备得到。本发明示例的一种具有多官能团化的环己烷化合物及其制备方法,利用碱催化来进行制备,实现了多步串联“一锅法”合成环己烷化合物。
Description
技术领域
本发明涉及有机化学合成方法技术领域,特别是涉及一种具有多官能团化的环己烷化合物及其制备方法。
背景技术
多官能团化的环己烷骨架作为一类独特的结构单元广泛存在于药物分子和天然产物中。如环萜类的薄荷醇(参照Xu,L.;Han,Y.;Chen,X.;Aierken,A.;Wen,H.;Zheng,W.;Wang,H.;Lu,X.;Zhao,Z.;Ma,C.;Liang,P.;Yang,W.;Yang,S.;Yang,F.Nat Common,2020,11,3790.)、姜科植物郁金中的榄香烯化合物(参照Iglesias,D.B.;Teijón.P.H.;González,R.R.;Fernández-Mateos,A.Eur.J.Org.Chem.2018,4926.)、第三代铂类抗癌药物奥沙利铂(参照Horasawa,S.;Kaneko,A.;Kotani,D.;Nakashima,S.;Bando,H.;Yoshino,T.Ann.Oncol.2018,29,ix32)。另外,该类骨架还在不对称催化中作为手性催化剂和手性配体表现出重要应用优势,如Trost配体被广泛应用于多种有机或金属不对称催化反应,且获得优异的对映选择性(参照Trost,B.M.;Fandrick,D.R.;Dinh,D.C.J.Am.Chem.Soc.2005,127,14186.)。此外,在化工行业,环己烷骨架衍生物也有广泛应用,如环保增塑剂环己烷-1,2-二甲酸二异辛酯(参照McMurray,J.W.;Zhou,Y.;Luo,H.-M.;Qu,J.Polymers,2017,667,55.)和凉味剂N-乙基-2-异丙基-5-甲基环己烷甲酰胺(参照Serra,S.;Fuganti,C.;Gatti,F.G.Eur.J.Org.Chem.2008,1031.)等。由此可见,多取代环己烷骨架是多种生物活性分子和工业用品的“优势基础单元”,如何高效便捷构建此类化合物成为有机合成的一大热点。
目前,针对该类骨架的合成主要是通过两组分环加成方式得到,如[4+2],[3+3]和[5+1]环加成反应[参照a)Huang,X.-F.;Liu,Z.-M.;Geng,Z.-C.;Zhang,S.-Y.;Wang,Y.;Wang,X.-W.Org.Biomol.Chem.2012,10,8794;b)Reyes,E.;Jiang,H.;Milelli,A.;Elaner,P.;Hazell,R.;K.A.Angew.Chem.;Int.Ed.2007,119,9362;c)Ma,W.;Fang,J.;Ren,J.;Wang,Z.Org.Lett.2015,15,4180;d)Akhtar,W.M.;Armstrong,R.J.;Frost,J.R.;Stevenson,N.G.;Donohoe,T.J.J.Am.Chem.Soc.2018,140,11916.]。而对于三组分串联方式来构建这类化合物的研究还有待进一步开发,其中通过三组分[2+2+2]串联反应合成环已烷化合物有少量的报道[参照a)Mao,Z.;Jia,Y.;Xu,Z.;Wang,R.Adv.Synth.Catal.2012,354,1401;b)Kuan,H.-H.;Chien,C.-H.;Chen,K.Org.Lett.2013,15,2880.]。而对于历经更具挑战性的[1+2+3]多组分串联“一锅法”途径来制备该类骨架还鲜有报道。因此,发展一种操作简便、催化高效、经济性好,且高化学选择性的化学方法来合成具有多官能团化的环己烷化合物,无论在科学研究还是工业应用领域中都将具有广阔的应用前景。
发明内容
