Description
技术领域
本发明涉及有机化合物制备领域,具体涉及通过共轭烯二炔酸与邻炔基苯胺在钯铜共催化下发生交叉环化氧化反应,制备多取代菲啶化合物的方法。
背景技术
菲啶类化合物以多种形式广泛的存在于自然界中,也是一些天然产物或者药物分子的基本框架(Walton,J.C.Molecules 2016,21,660;Zhang,B.;Studer,A.Chem.Soc.Rev.2015,44,3505;Tumir,L.-M.;M.R.;Piantanida,I.BeilsteinJ.Org.Chem.2014,10,2930)。
因此,菲啶类化合物引起了众多化学家的极大关注。现有的方法主要有以下几类:1、通过邻位官能团化的联芳香化合物来制备(Zhao,H.-B.;Liu,Z.-J.;Song,J.;Xu,H.-C.Angew.Chem.,Int.Ed.2017,56,12732;Raju,S.;Annamalai,P.;Chen,P.-L.;Liu,Y.-H.;Chuang,S.-C.Org.Lett.2017,19,4134;Tang,J.;Sivaguru,P.;Ning,Y.;Zanoni,G.;Bi,X.Org.Lett.2017,19,4026;Hu,Z.;Dong,J.;Men,Y.;Li,Y.;Xu,X.Chem.Commun.2017,53,1739),2、苯型化合物过渡金属催化的分子间环化(Maestri,G.;Larraufie,M.-H.;Derat,Ollivier,C.;Fensterbank,L.;E.;Malacria,M.Org.Lett.2010,12,5692;Takamatsu,K.;Hirano,K.;Miura,M.Angew.Chem.,Int.Ed.2017,56,5353),3、通过发生连续的C-N键的形成以及C-C键偶联的[3+3]环化路线(Banerji,B.;Bera,S.;Chatterjee,S.;Killi,S.K.;Adhikary,S.Chem.—Eur.J.2016,22,3506;Bhowmik,S.;Pandey,G.;Batra,S.Chem.—Eur.J.2013,19,10487),4、过渡金属催化的[2+2+2]的环三聚反应(Vollhardt,K.P.C.Acc.Chem.Res.1977,10,1;Li,Y.;Zhu,J.;Zhang,L.;Wu,Y.;Gong,Y.Chem.—Eur.J.2013,19,8294)。
现有的方法通常具有反应条件剧烈,区域选择性差,产率不高等缺点,限制了多取代菲啶类化合物的发展。因此,如何高效的合成多取代菲啶类化合物仍具有重要意义。
发明内容
本发明提供了一种多取代菲啶的制备方法,具有较高的收率,产物具有多取代基多官能团,原料易得,操作简便,反应条件温和。
具体技术方案如下:

所述的多官能团菲啶衍生物结构如结构式(I)所示,
所述的结构式(I)中,R1,R2和R4各自独立的为烷基或芳基,R3为H、CH3O、CH3、F、Cl、Br、CN或CF3,R5为氢;
所述的共轭烯二炔酸如结构式(II)所示,
所述的邻炔基苯胺如结构式(III)所示,
所述的结构式(I)和结构式(II)、(III)中,R1~R4的定义相同。
将共轭烯二炔酸和邻炔基苯胺、钯催化剂和铜盐溶于有机溶剂中,共轭烯二炔酸与邻炔基苯胺的摩尔比为1:1~4,气氛为空气或氧气,反应压力为1~1.5个标准大气压,在20~80℃温度下反应1~40小时;反应结束后,得到的产物多取代菲啶化合物可通过常规的提纯方法获得,如硅胶柱色谱、结晶等分离纯化方法。
所述的气氛优选为氧气,使得共轭烯二炔酸与邻炔基苯胺反应更加完全。
所述的钯催化剂为醋酸钯、三氟醋酸钯、氯化钯、二(三苯基膦)醋酸钯或二(三苯基膦)氯化钯;所述的铜盐为氯化亚铜、氯化铜、溴化亚铜、溴化铜或碘化亚铜。钯催化剂的用量为共轭烯二炔酸的1~20mol%(摩尔比),优选为1~5mol%(摩尔比);铜盐的用量为共轭烯二炔酸的5~200mol%(摩尔比),优选为10~50mol%(摩尔比)。
所述的有机溶剂为四氢呋喃、乙腈、N,N-二甲基甲酰胺、N,N-二甲基乙酰胺或二甲亚砜;所述的有机溶剂进一步优选为N,N-二甲基甲酰胺。
本发明提供的多官能团菲啶衍生物的制备方法可优选为,共轭烯二炔酸与邻炔基苯胺类化合物在钯铜共催化下得到所述的多官能团菲啶羧酸衍生物,如反应式1所示。
反应式1:
本发明提供的多官能团菲啶衍生物的制备方法也可优选为,共轭烯二炔酸与邻炔基苯胺类化合物在钯铜共催化下反应完后,产物做甲基化处理得到所述的多官能团菲啶酯类衍生物,如反应式2所示。
反应式2:
本发明具有以下优点:1)反应具有较高的收率,产物具有多取代基多官能团等优点。2)原料易得,操作简便,反应条件温和。3)绿色氧气做氧化剂,避免使用大量氧化剂及对环境的污染。4)具有较好的区域选择性和化学选择性。
本方法所得的相应的菲啶类化合物的产率为77-93%。
