一种α-芳基、杂芳基或烯基-α,α-二氟甲基类化合物的制备 方法
技术领域
本发明涉及一种α-芳基、杂芳基或烯基-α,α-二氟甲基类化合物的制备方法。
背景技术
α-芳基或杂芳基-α,α-二氟甲基类化合物及其衍生物砌块在生物医药、农药和材料科学等方面都有着广泛的应用。然而,传统的合成α-芳基或杂芳基-α,α-二氟烷基砌块的方法中,通常是由羰基通过DAST或者Deoxofluor制得(例如,Markovsi,L.N.;Pahinnik,V.E.;Kirsanov,A.V.Synthesis 1973,787.(b)Middleton,W.J.J.Org.Chem.1975,40,574.)。但是,这些方法通常具有反应步骤冗长、官能团兼容性不好、某些反应需要用到一些剧毒的氟化剂等缺点。
最新发展的过渡金属催化的α-芳基或杂芳基-α,α-二氟甲基类化合物及其衍生物的砌块合成方法((a)Fujikawa,K.Fujioka,Y.Kobayashi,A.Amii,H.Org.Lett.2011,13,5560.(b)Fujiwara,Y.Dixon,J.A.Rodriguez,R.A.Baxter,R.D.Dixon,D.D.Collins,M.R.Blackmond,D.G.Baran,P.S.J.Am.Chem.Soc.2012,134,1494.(c)Fier,P.S.Hartwig,J.F..J.Am.Chem.Soc.2012,134,5524.(d)Prakash,G.K.S.Ganesh,S.K.Jones,J.-P.Kulkarni,A.Masood,K.Swabeck,J.K.Olah,G.A.Angew.Chem.Int.Ed.2012,51,12090.(e)Gu,Leng,Y.X.Shen,Q.Nat.Commun.2014,5,5405.(f)Matheis,C.Goossen,K.L.Org.Lett.2014,16,5984.(g)Xu,L.Vicic,D.A.J.Am.Chem.Soc.2016,138,2536.)在一定程度上解决了这类化合物合成的困难。但是,这些方法仍然存在以下两个方面的不足:1,合成所使用的二氟甲基试剂价格昂贵、合成步骤繁琐、需要通过多步复杂合成并且难以大量制备;2,合成方法官能团兼容性差、催化剂用量高、反应条件苛刻等不足。
因此,探索一种二氟甲基源廉价易得,并且合成方法高效简便、官能团兼容性好、催化剂用量低、反应条件温和的合成α-芳基、杂芳基或烯基-α,α-二氟甲基类化合物及其衍生物的方法具有显著的意义。
发明内容
本发明所要解决的技术问题在于克服现有技术中α-芳基、杂芳基或烯基-α,α-二氟甲基砌块的合成方法或具有反应步骤冗长、官能团兼容性差、涉及剧毒氟化剂等缺点;或具有合成所使用的二氟甲基试剂价格昂贵、合成步骤繁琐、需要通过多步复杂合成、难以大量制备等缺点;或具有合成方法官能团兼容性差、催化剂用量高、反应条件苛刻等不足,因而提供了一种α-芳基、杂芳基或烯基-α,α-二氟甲基类化合物的制备方法,本发明的制备方法以廉价的氟化工基础原料氯二氟甲烷为作为氟源、高效简便、合成方法官能团兼容性好、催化剂用量低、反应条件温和。
本发明的发明人通过长期而深入的研究,发现了一种以钯盐为催化剂,以芳基酚为助催化剂,经过偶联反应合成α-芳基、杂芳基或烯基-α,α-二氟甲基结构化合物及其衍生物的简便方法。该方法具有反应步骤短且原料简单易得,官能团适用范围广,可避免使用剧毒试剂等优点,因此,本发明所述的制备方法更具经济性和简洁性。在此基础上,发明人完成了本发明。
