Description
技术领域
本发明涉及合成含手性咪唑吡啶酰胺类的化合物及其制备方法,以及该化合物与钴共催化烯烃的不对称硼氢化反应中的用途。
背景技术
有机硼酯化合物是一类非常重要的有机合成砌块,能选择性的构建不同的化学键(C-C、C-O、C-N、C-X等)[D.Leonori,;V.K.Aggarwal,Angew.Chem.,Int.Ed.2015,54,1082.]。在药物研发中,硼酸常作为关键的合成中间体,另外还能替代羧酸药物的羧基以改善药效,对新药研发具有重要意义。近年来发展了许多立体专一性的转化手性硼酯的方法[C.Sandford,V.K.Aggarwal,Chem.Commun.2017,53,5481.],从而得到其他一系列的含有不同官能团的手性分子,因此对于手性硼酯的合成显得尤为重要。在合成手性硼酯的方法中,烯烃的不对称硼氢化反应由于原料易得、原子经济性好,引起了合成化学家的特别关注。
硼氢化反应,即硼氢键加成到碳碳双键或者碳碳叁键上的反应(广义的硼氢化反应还包括碳氧双键、碳氮双键等不饱和键的硼氢化),最早由Brown发现并发展[H.C.Brown,B.C.S.Rao,J.Am.Chem.Soc.1956,78,2582]。对于苯乙烯和β位取代的苯乙烯类化合物的不对称硼氢化反应,存在区域和立体选择性问题,传统的非催化不对称硼氢化反应通常得到反马氏加成产物而且需要用到当量的难以制备的手性硼试剂,因而存在一定的局限性。而金属催化的不对称硼氢化反应通过金属和手性配体共同调控反应的区域和立体选择性,因而为烯烃的马氏选择性的不对称硼氢化反应提供了一种重要的途径。
1989年,Hayashi和Ito报道了Rh催化的高度立体选择性苯乙烯类化合物的马氏硼氢化反应,该反应使用了手性BINAP配体,但需要在-78℃下进行[T.Hayashi,Y.Matsumoto,Y.Ito,J.Am.Chem.Soc.1989,111,3426]。1993年,Brown等使用了手性的P,N配体[J.M.Brown,D.I.Hulmes,T.P.Layzell,J.Chem.Soc.Chem.Commun.1993,1673.],在室温下实现了苯乙烯类底物不对称马氏硼氢化反应。在接下来的10年里,许多其他Rh催化的苯乙烯类化合物不对称硼氢化反应也相继报道[C.M.Crudden,D.Edwards,Eur.J.Org.Chem.2003,4695]。2009年,Yun等使用CuCl/Tangphos催化体系实现了苯乙烯类底物高度区域和立体选择性的不对称马氏硼氢化反应,这是廉价金属催化苯乙烯类化合物不对称马氏硼氢化反应的首个报道[D.Noh,H.Chea,J.Ju,J.Yun,Angew.Chem.Int.Ed.2009,48,6062]。之后,他们使用了Segphos衍生的配体实现了高度立体选择性的β位取代的苯乙烯类化合物的不对称硼氢化反应[D.Noh,S.K.Yoon,J.Won,J.Y.Lee,J.Yun,Chem.Asian J.2011,6,1967.]。
铁钴由于价格低廉,储量丰富,低毒以及环境友好,在过去的十年里,在不对称催化领域获得了广泛的关注,并得到了较快的发展[H.Pellissier,H.Clavier,Chem.Rev.2014,114,2775;K.Gopalaiah,Chem.Rev.2013,113,3248.]。一些铁或者钴络合物催化的烯烃不对称硼氢化反应己经被报道[L.Zhang,Z.Zuo,X.Wan,Z.Huang,J.Am.Chem.Soc.,2014,136,15501.;J.H.Chen,T.Xi,X.Ren,B.Cheng,J.Guo,Z.Lu,Org.Chem.Front.2014,1,1306;H.Y.Zhang,Z.Lu,Acs Catalysis2016,6,6596.]。从这些报道的例子中,我们可以看出在烯烃的不对称硼氢化反应中,这些廉价金属完全有可能取代之前发展的贵重金属催化剂。但到目前为止尚未报道铁或钴催化的苯乙烯类底物马氏加成的不对称硼氢化反应,而且之前廉价金属铜催化的苯乙烯类底物使用了相对难于合成的P配体。因此,寻找适合与铁钴配位的其他易制备的配体,从而实现高区域和立体选择性的苯乙烯和1,2-二取代烯烃的不对称硼氢化反应的方法是一个很有意义的课题。
