Description
技术领域
本发明属于化学催化领域,具体地说,涉及一类手性单膦配体及其制备方法。
背景技术
在不对称催化反应中,配体的影响极其关键,由于配体没有通用性,底物结构的变化,常常会导致催化剂活性和对映选择性的显著改变,这就需要合适的配体与底物相互匹配。因此手性配体的设计合成与新的催化反应无疑都是不对称催化开发研究的热点(Noyori,R;Ohkuma,T.Angew.Chem.Int.Ed.2002,41,2008–2022.),前者着重新配体的设计合成,后者则进行新反应的探索。手性膦配体是不对称催化过程中应用最广泛、最为成功的几类配体之一,在不对称催化的发展中起着至关重要的作用。在手性双膦配体中,已发现配体的二面角对不对称氢化的活性和对映选择性有着重要影响,合适的二面角往往能得到很好的对映选择性(Zhang,X.;et al.J.Org.Chem.2000,65,6223.Chan,A.S.C.;etal.J.Am.Chem.Soc.2006,128,5955.)。近年来,手性单膦配体特别是联芳基单膦配体,由于其广泛的手性诱导能力尤其在不对称C-C键形成方面的强大能力而备受关注,1991年Hayashi等合成了(S)-2-二苯基膦-2'-甲氧基-1,1'-联萘(MeO-MOP),并成功应用于非官能团烯烃的不对称硅氢化反应中(Uozumi,Y;Hayashi,T.J.Am.Chem.Soc.1991,113,9887-9888.)。2000年Buchwald等开发了一系列轴手性联萘单磷配体(Yin,J.;Buchwald,S.L.J.Am.Chem.Soc.2000,122,12051.),并成功应用于不对称Suzuki偶联反应中。邱立勤等人相继开发了二面角可调的手性联苯基O,P-单膦配体和N,P-单膦配体(Org.Lett.2012,14,1966;Adv.Synth.Catal.2012,354,239;CN102516300A;CN102532196A.),应用于不对称Suzuki偶联反应时,获得了比联萘基单膦配体MOP及上述Buchwald配体更佳的效果。但不对称Suzuki偶联反应底物对配体的要求非常严格,应用已有配体获得成功的催化实例还非常有限,对杂环化合物以及大位阻联芳的不对称偶联,目前还缺乏有效的配体和催化体系,急需开发新型手性配体和催化体系来解决手性联芳基化合物的不对称催化合成这一热点难题。
