Description
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 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
