Description

一种直接构建高光学活性四取代联烯酸类化合物的方法 技术领域
本发明属于化学合成技术领域，具体涉及一种直接构建高光学活性四取代联烯酸类化合物的方法。
技术背景
含轴手性的联烯化合物广泛存在于天然产物及药物分子中，是一类非常重要的化合物(Ref:(a)Hoffmann-
Figure PCTCN2019123005-appb-000001
A.；Krause,N.Angew.Chem.,Int.Ed.2004,43,1196.(b)Rivera-Fuentes,P.；Diederich,F.Angew.Chem.,Int.Ed.2012,51,2818.)。如何构建四取代的手性季碳中心，在过去十几年里得到广泛的研究，并取得了***的成果，然而相对于构建含有四取代的手性季碳中心的化合物，四取代的轴手性联烯化合物的合成依然存在较大的挑战，报道的方法仍十分有限，主要原因在于联烯分子中含有一个在空间上互相垂直的累积碳碳双键，联烯基1,3-位的取代基处在距离较远的互相垂直的空间上，相比于中心手性的形成它需要更大的手性屏蔽环境去诱导其轴手性的生成(Ref:(a)Hayashi,T.；Tokunaga,N.；Inoue,K.Org.Lett.2004,6,305.(b)Qian,D.；Wu,L.；Lin,Z.；Sun,J.Nat.Commun.2017,8,567.(c)Hashimoto,T.；Sakata,K.；Tamakuni,F.；Dutton,M.J.；Maruoka,K.Nat.Chem.2013,5,240.(d)Mbofana,C.T.；Miller,S.J.J.Am.Chem.Soc.2014,136,3285.(e)Wang,G.；Liu,X.；Chen,Y.；Yang,J.；Li,J.；Lin,L.；Feng,X.ACS Catal.2016,6,2482.(f)Tang,Y.；Xu,J.；Yang,J.；Lin,L.；Feng,X.；Liu,X.Chem.2018,4,1658.(g)Tap,A.；Blond,A.；Wakchaure,V.N.；List,B.Angew.Chem.,Int.Ed.2016,55,8962)。
手性联烯酸类化合物主要通过消旋联烯酸化合物或联烯腈化合物的拆分方式(Ref:(a)Ma,S.；Wu,S.Chem.Commun.2001,0,441.(b)Ao,Y.-F.；Wang,D.-X.；Zhao,L.；Wang,M.-X.J.Org.Chem.2014,79,3103.)和手性联烯酸酯的水解方式制备得到(Ref:(a)Marshall,J.A.；Bartley,G.S.；Wallace,E.M.J.Org.Chem.1996,61,5729.(b)Yu,J.；Chen,W.-J.；Gong,L.-Z.Org.Lett.2010,12,4050)，并且上述方法对四取代联烯酸类化合物的制备的例子非常有限。通常，这些方法有较大的局限性，比如反应产率低，底物范围窄，官能团容忍性不好，原子经济学差等。因此发展一种从简单易得的原料出发，高效率、高对映选择性的合成四取代轴手性 联烯酸类化合物的方法将是对现有合成方法的重要突破。
