Description
技术领域:
本发明涉及化学技术领域,具体涉及一种以N,N-二取代酰肼为配体的铜催化C-N偶联方法。
背景技术:
胺类化合物广泛存在于具有生理活性的天然和非天然产物、药物,农药、材料中。因此,C-N键的形成一直受到有机合成化学家的广泛重视。(Magano,J.;Dunetz,J.R.,Chemical reviews 2011,111,2177-250.)。
由于铜便宜易得,所用配体比较稳定,低毒,与其他贵金属相比,铜催化芳基卤代物与胺的反应越来越受到人们的关注。然而早期的Ullmann反应,反应条件比较苛刻(如:高温、强碱、化学计量的铜或铜盐和长反应时间)和中等的反应产率,从而限制了其大规模的推广应用。(Jiang,Y.;Ma,D.,Assembly of N-Containing Heterocycles via Pd-and Cu-Catalyzed C-N Bond formation Reaction in:Amination and Formation of sp2C-NBonds.Springer:Springer-Verlag Berlin Heidelberg,2013;Monnier,F.;Taillefer,M.,Copper-Catalyzed C(aryl)–N Bond Formation in:Amination and Formation ofsp2C–N Bonds.Springer-Verlag Berlin Heidelberg,2013;Ley,S.V.;Thomas,A.W.,Angew.Chem.,Int.Ed.2003,42,5400-5449.)。近年来,铜催化的C-N偶联反应取得了新的进展,突破了很多局限,拓宽了反应前景,尤其表现在对活性很低的芳基氯的活化方面。(Aubin,Y.;Fischmeister,C.;Thomas,C.M.;Renaud,J.L.;Chem.Soc.y rev.2010,39,4130-45;Ma,D.;Cai,Q.;Zhang,H.;Org.Lett.2003,5,2453-2455;Zhou,W.;Fan,M.;Yin,J.;Jiang,Y.;Ma,D.;J.Am.Chem.Soc.2015,137,11942-5;Monier,F.;Taillefer,M.;Angew.Chem.,Int.Ed.2009,48,1534-1544;Huang,M.;Lin,X.;Zhu,X.;Peng,W.;Xie,J.;Wan,Y.;Eur.J.Org.Chem.2011,4523–4527.)。
尽管铜催化偶联反应已经取得了很大进展,但与Buchwald-Hartwig反应相比较仍旧面临着巨大的挑战,如:1)铜催化芳基氯的胺化底物适用范围比较窄。2)在10-80℃范围内,催化剂的转化次数和转换率都比较低(Monnier,F.;Taillefer,M.,Copper-CatalyzedC(aryl)–N Bond Formation in:Amination and Formation of sp2C–N Bonds.Springer-Verlag Berlin Heidelberg,2013;Xie,R.;Fu,H.;Ling,Y.;Chem Commun 2011,47,8976-8.)。另外,对于铜催化的Ullmann C-N偶联反应,应用于工业生产由于其需要加热,在节能方面仍有缺陷(Brahmachari,G.,Room Temperature Organic Synthesis.ElsevierInc.2015.),在工业生产上仍然面临很大的挑战。
近年来,我们开发了各种水相体系中的N-芳基化方法(ZL 201010102104.5,ZL200910040649.5),也存在着一些缺陷,如反应温度过高、底物适用范围较窄等。
于是,发展一种温和条件下,Ullmann C-N偶联反应,不管在学术方面还是工业生产方面,都具有重大意义,尤其对于一些对热比较敏感的化合物。因此,提供一种室温条件,环境友好,底物适用范围广的芳基卤代物与胺的C-N偶联方法,是该类反应的客观要求,也必将有很好的应用前景。
本发明是在国家自然科学基金(21272287)资助下而进行的研究。
发明内容:
本发明的目的是克服现有技术中存在的缺点,提供一种以N,N-二取代酰肼为配体的铜催化C-N偶联方法,该方法反应条件温和,化学选择性高,得到的产物收率更高,且底物范围广。
本发明是通过以下技术方案予以实现的:
