背景技术

近二十年来，氮杂环卡宾作为有机小分子催化剂得到了化学家们的广泛关注[(a)D.Enders and T.Balensiefer,Acc.Chem.Res.2004,37,534.(b)D.Enders,O.Niemeier,A.Henseler,Chem.Rev.2007,107,5606；(c)V.Nair,S.Vellalath,B.P.Babu,Chem.Soc.Rev.2008,37,2691；(d)A.T.Biju,N.Kuhl,F.Glorius,Acc.Chem.Res.2011,44,1182；(e)A.Grossmann,D.Enders,Angew.Chem.Int.Ed.2012,51,314；Angew.Chem.2012,124,320；(f)J.Izquierdo,G.E.Hutson,D.T.Cohen,K.A.Scheidt,Angew.Chem.Int.Ed.2012,51,11686；Angew.Chem.2012,124,11854；(g)S.J.Ryan,L.Candish,D.W.Lupton,Chem.Soc.Rev.2013,42,4906；(h)J.Mahatthananchai,J.W.Bode,Acc.Chem.Res.2014,47,696；(i)M.N.Hopkinson,C.Richter,M.Schedler,F.Glorius,Nature2014,510,485.]。

随着有机化学家们对氮杂环卡宾催化剂研究的日趋成熟，氮杂环卡宾催化的底物范围和反应类型丰富扩大，在有机合成中显示出了重要的作用。这其中陆续出现的一些优秀的氮杂环卡宾催化剂，在这一领域的发展中起到了举足轻重的作用。其中，具有并环结构的三氮唑卡宾催化剂在手性控制上具有显著的优势，在不对称合成中具有重要的应用。[(a)D.Enders,O.Niemeier,T.Balensiefer,Angew.Chem.,Int.Ed.2006,45,1463.(b)M.He,J.R.Struble,J.W.Bode,J.Am.Chem.Soc.2006,128,8418.(c)Q.Liu,S.Perreault,and T.Rovis,J.Am.Chem.Soc.2008,130,14066.(d)D.A.DiRocco,K.M.Oberg,D.M.Dalton,T.Rovis,J.Am.Chem.Soc.2009,131,10872.(e)L.Baragwanath,C.A.Rose,K.Zeitler,S.J.Connon,J.Org.Chem.2009,74,9214；(f)S.De Sarkar,A.Studer,Angew.Chem.2010,122,9452；Angew.

寻找新型骨架的手性氮杂环卡宾催化剂并且使之适用于一些反应或者更多反应并能具有好的催化活性及对映选择性一直是化学工作者研究的热点之一。

为了解决这些问题，我们从商业可得的手性苯丙氨酸甲酯盐酸盐出发合成了具有3,4-二氢异喹啉骨架的手性氮杂环卡宾催化剂，该催化剂合成步骤简单，并容易通过重结晶提纯，在诸多氮杂环卡宾催化的反应中都具有非常好的效果。因此该催化剂对于氮杂环卡宾催化剂骨架的丰富和反应条件的优化都具有重要的意义。
