Abstract
本发明属于有机合成化学的技术领域,公开了一种利用金属盐催化剂,二甲亚砜作为一碳合成子,咪唑和酮类衍生物制备β-氨基胺酮的简洁、高效的新方法,制备了系列β-氨基胺酮类化合物。本发明克服了目前现有的制备β-氨基胺酮类化合物的局限性,避免了传统方法有毒试剂甲醛类似物的参与而导致对环境以及人体毒害较大的缺点;首次实现了使用低毒的二甲亚砜以及N,N-二甲基甲酰胺(DMF),N,N-二甲基乙酰胺(DMA),N-甲基吡咯烷酮(NMP)作为一碳合成子合成了系列β-氨基胺酮,拓展了β-氨基胺酮类化合物合成的新途径。本发明具有操作简单,高效,原料、试剂和催化剂易得,适用于合成各种β-氨基胺酮类化合物,适用于大规模的工业生产。
Description
技术领域:
本发明属于有机合成化学的技术领域,公开了一种金属盐催化酮类衍生物、咪唑和一碳合成子二甲亚砜制备β-氨基酮的新方法。
背景技术:
曼尼希反应(Mannich反应,简称曼氏反应),也称作胺甲基化反应,是含有活泼氢的化合物与甲醛和二级胺或氨缩合,生成β-氨基(羰基)化合物的三组分有机化学反应(Verkade,J.M.M.;van Hemert,L.J.C.;Quaedflieg,P.J.L.M.;Rutjes,F.P.J.T.Chem.Soc.Rev.37,29,(2008))。一般醛亚胺与α-亚甲基羰基化合物的反应也被看做曼尼希反应。反应的产物β-氨基(羰基)化合物称为“曼尼希碱”,简称曼氏碱(Mannich,C.;Krosche,W.Arch.Pharm.250,674,(1912))。反应中的胺一般为二级胺,如哌啶、二甲胺等。如果用一级胺,反应后的缩合产物在氮上还有氢,可以继续发生反应,故有时也可根据需要使用一级胺,一级胺与甲醛常温下会迅速脱水,形成希夫碱。如果用三级胺或芳香胺,反应中无法生成亚胺离子,停留在季铵离子一步。
在此之前合成β-氨基酮类化合物一般都会用到醛类化合物。甲醛是最常用的醛,一般用它的水溶液、三聚甲醛或多聚甲醛。除甲醛外,也可用其他醛。反应一般在水、乙酸或醇中进行,加入少量盐酸以保证酸性。然而醛类化合物对环境,对人体均不友好。而且之前曼氏反应通常需在高温下和质子溶剂中进行,反应时间长,容易生成副产物。近年来,利用叔胺的氧化两组份曼尼西反应作为一种重要的方法补充,能够合成一些常规方法难以得到的曼尼西碱产物(Li,Z.;Li,C.-J.J.Am.Chem.Soc.127,3672,(2005),Shen,Y.;Li,M.;Wang,S.;Zhan,T.;Tan,Z.;Guo,C.-C.Chem.Commun.953,(2009),Chu,L.;Zhang,X.;Qing,F.-L.Org.Lett.11,2197,(2009),Zhang,G.;Zhang,Y.;Wang,R.Angew.Chem.,Int.Ed.50,10429,(2011),Zhao,G.;Yang,C.;Guo,L.;Sun,H.;Chen,C.;Xia,W.Chem.Commun.48,2337,(2012),Zhang,G.;Ma,Y.;Wang,S.;Kong,W.;Wang,R.Chem.Sci.4,2645,(2013))。然而这种方法也面临底物范围不够宽泛的困扰。所以发展绿色环保、新型高效的合成β-氨基酮类化合物的方法特别重要(Chem-Asian.J.2015,10,536)。
