Description
技术领域
本发明涉及一种基于手性β-氨基膦骨架的膦-亚磷酰胺酯配体及其制备方法。本发明还涉及上述配体在C=C、C=N、C=O等双键的不对称氢化反应中的应用。
背景技术
催化不对称氢化是不对称合成中的核心技术,是合成光学纯手性药物、农药、食品添加剂和香料的最有效方法之一,而手性配体的设计合成是实现这一核心技术的关键因素。不对称催化氢化反应,因其原子经济性高,一直备受人们关注,成为获得各手性化合物最直接、最有效的方法之一。在不对称催化氢化的发展过程中,手性膦配体的设计与合成占据着十分重要的地位[(a)Borner A. Phosphorus Ligands in Asymmetric Catalysis,Wiley-VCH,Weinheim,2008;(b) Zhou,Q.-L.Privileged Chiral Ligands andCatalysts,Wiley-VCH,Weinheim,2011.]。
20世纪70年代,DIOP和DIPAMP的成功,使得C2对称性的配体设计理念深入人心,人们发展了许多具有C2对称性的手性双膦配体[(c)Dang,T.P.;Kagan, H.B.J.Chem.Soc.,Chem.Commun.1971,481;(d)Vineyard,B.D.;Weinkauff,D.J. J.Am.Chem.Soc.1977,99,5946.];20世纪80年代,BINAP的兴起,逐步推动了轴手性配体的发展;20世纪90年代,随着Duphos和BPE配体的成功应用,环状膦配体的设计理念得到了大家的认可,一些环状的磷手性中心配体被相继报道 [(e)Berthod,M.;Lemaire,M.Chem.Rev.2005,105,1801;(f)Wang,C.-J.;Gao,F.J. Am.Chem.Soc.2008,130,17250;(g)Tang,W.;Chan,A.S.C.Angew.Chem.,Int. Ed.2009,48,9135.]。近来的研究表明非对称性杂化的手性膦配体在许多不对称催化反应中表现出与C2对称的手性双膦配体相当甚至更为优异的活性和光学选择性。这些非对称杂化的手性膦配体在不对称催化反应中的成功应用极大的拓展了手性膦配体的设计理念丰富了手性膦配体的种类。膦-亚磷酰胺配体代表了重要的一类非对称杂齿齿磷配体,在各种不对称转化中均显示出优异的结果。因此开发新的膦-亚磷酰胺酯配体具有重要的理论和现实意义。
