Description
技术领域
本发明涉及一种高效多样化合成2-吡啶酮类化合物的方法,属于有机合成领域。
背景技术
2-吡啶酮是一种重要的结构单元,广泛存在于许多具有生物活性的天然产物和医药分子结构中[a)Q.Li,L.A.Mitscher,L.L.Shen,Med.Res.Rev.2000,20,231;f)J.L.Medina-Franco,K.Martínez-Mayorga,C.Juárez-Gordiano,R.Castillo,ChemMedChem,2007,2,1141]。
目前,2-吡啶酮类化合物的合成方法有许多,但是从简单的原料出发,高效制备2-吡啶酮类化合物的方法却鲜有报道。目前已知的主要合成方法有四种:第一种是利用吡啶的水解直接得到2-吡啶酮类化合物[P.Schrcder,T.Fcrster,S.Kleine,C.Becker,A.Richters,S.Ziegler,D.Rauh,K.Kumar,H.Waldmann,Angew.Chem.Int.Ed.2015,54,12398.]。但是该方法底物范围受限;第二种是利用经典的亲电取代反应[a)R.E.Cline,R.M.Fink,K.Fink,J.Am.Chem.Soc.1959,81,2521.],但是该方法反应选择性差,底物范围受限;第三种是利用非环状前体来构建2-吡啶酮[a)H.J.Jessen,A.Schumacher,T.Shaw,A.Pfaltz,K.Gademann,Angew.Chem.Int.Ed.2011,50,4222;Angew.Chem.2011,123,4308;b)M.Fujii,T.Nishimura,T.Koshiba,S.Yokoshima,T.Fukuyama,Org.Lett.2013,15,232.],但该方法底物类型特殊且反应条件苛刻;第四种是利用过渡金属碳氢键活化的策略来实现吡啶酮类化合物的官能团化[K.Hirano,M.Miura,Chem.Sci.2018,9,22.],但该方法一次只能选择性构建一根化学键。
发明内容
