含二氟烷基取代的芳基或杂芳基化合物、制备方法和应用
技术领域
本发明涉及一种含二氟烷基取代的芳基或杂芳基化合物、制备方法和应用。
背景技术
二氟烷基取代的芳烃/杂芳烃化合物在医药、农药和材料科学领域都有着重要的应用。传统的引入二氟亚甲基主要是通过脱氧氟化试剂例如DAST(即二乙胺基三氟化硫),对羰基、醛基进行脱氧氟化,或者在氧化剂存在下,利用亲核氟化试剂HF-Py、TBABF等对缩硫酮或腙进行氟化。但是由于氟化试剂往往活性太高,反应复杂,很多重要官能团不兼容,使得该方法在合成复杂含二氟亚甲基化合物时不适用,从而限制了该方法的应用。虽然最近几年向芳环引入二氟烷基的方法取得了很大的进展,但是发展一些过渡金属催化的廉价、广谱通用的方法还是非常重要的。
在氟烷基取代芳烃化合物中,我们关注的是一类含二氟烷基取代的芳烃/杂芳烃化合物。由于二氟亚甲基可以作为羰基的生物电子等排体,再加上氟原子独特的理、化、生物性质,这类化合物在生命科学领域具有非常重要的应用((a)J.O.Link,J.G.Taylor,L.Xu,M.Mitchell,H.Guo,H.Liu,D.Kato,T.Kirschberg,J.Sun,N.Squires,J.Parrish,T.Keller,Z.-Y.Yang,C.Yang,M.Matles,Y.Wang,K.Wang,G.Cheng,Y.Tian,E.Mogalian,E.Mondou,M.Cornpropst,J.Perry,M.C.Desai,J.Med.Chem.2014,57,2033;(b)JR.T.R.Burke,K.Lee,Acc.Chem.Res.2003,36,426;(c)Z.-Y.Zhang,Acc.Chem.Res.2003,36,385.)。目前过渡金属催化的合成该类化合物的方法取得了一定的进展,然而也只有少量的几例((a)K.Fujikawa,Y.Fujioka,A.Kobayashi,H.Amii,Org.Lett.2011,13,5560;(b)Z.Feng,F.Chen,X.Zhang,Org.Lett.2012,14,1938;(c)Z.Feng,Y.-L.Xiao,X.Zhang,Org.Chem.Front.2014,1,113;(d)Z.Feng,Q.-Q.Min,Y.-L.Xiao,B.Zhang,X.Zhang,Angew.Chem.2014,126,1695;Angew.Chem.,Int.Ed.2014,53,1669;(e)Q.-Q.Min,Z.Yin,Z.Feng,W.-H.Guo,X.Zhang,J.Am.Chem.Soc.2014,136,1230;(f)S.Ge,W.Chaladj,J.F.Hartwig,J.Am.Chem.Soc.2014,136,4149;(g)C.Guo,R.-W.Wang,F.-L.Qing,J.Fluorine Chem.2012,143,135.(h)Y.-L.Xiao,W.-H.Guo,G.-Z.He,Q.Pan,X.Zhang,Angew.Chem.2014,126,10067;Angew.Chem.Int.Ed.2014,53,9909.),且这些方法仍然存在一些不足,例如:反应条件苛刻,催化剂昂贵,官能团兼容性不好,广谱性不好等。基于钯催化的非活化的二氟烷基取代芳基/杂芳基化合物合成方法还没有文献报道。Y.-L.Xiao,W.-H.Guo,G.-Z.He,Q.Pan,X.Zhang,Angew.Chem.2014,126,10067;Angew.Chem.Int.Ed.2014,53,9909是基于镍催化的芳基硼酸与官能团化的二氟烷基卤代物的交叉偶联反应,反应廉价、高效、简洁,但是该反应仅对官能团活化的二氟烷基卤代物(该类化合物的共性是都具有共轭键,能对C-Br键进行活化)适用,例如

Figure BDA0000935171630000022
而对非活化的二氟烷基卤代物(即没有共轭基团对C-Br键活化,C-Br键非常惰性)并不起作用。因此,探索一种高效简便、官能团兼容性好、催化剂廉价且用量低、反应条件温和的合成含二氟烷基取代的芳基/杂芳基化合物的方法具有非常重要的意义。
发明内容
本发明所要解决的技术问题是为了克服现有的含二氟烷基取代的芳基或杂芳基化合物的制备方法中存在的反应条件苛刻,催化剂昂贵,官能团兼容性不好,底物适用范围窄,广谱性不好等缺陷,而提供了一种含二氟烷基取代的芳基或杂芳基化合物、制备方法和应用。本发明的制备方法原料简单易得,反应步骤少,转化率和反应收率高,操作简单,催化剂廉价易得,成本低,官能团兼容性好,底物适用范围广,广谱性强,可避免使用剧毒性试剂,安全性高,具有良好的工业化应用前景。
本发明主要是通过以下技术方案解决上述技术问题的。
本发明提供了一种如式C所示的含二氟烷基取代的芳基或杂芳基化合物的制备方法,其包括下列步骤:溶剂中,在碱、配体、催化剂和添加剂存在的条件下,将如式A所示的化合物和如式B所示的化合物进行如下所示的Suzuki偶联反应,制得如式C所示的化合物,即可;
