Description
技术领域
本发明属于化学领域。具体地,本发明涉及一种钯催化α-芳基、杂芳基或烯基-α,α-二氟烯丙基结构的合成方法。
背景技术
α-芳基、杂芳基或烯基-α,α-二氟烯丙基机构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、杂芳基或烯基-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.(c)Lal,G.S.;Pez,G.P.;Pesaresi,R.J.;Prozonic,F.M.;Cheng,H.J.Org.Chem.1999,64,7048.)。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、杂芳基或烯基-α,α-二氟烷基结构化合物及其衍生物的砌块合成方法((a)Schwaebe,M.K.;McCarthy,J.R.;Whitten,J.P.TetrahedronLett.2000,41,791.(b)Feng,Z.;Chen,F.;Zhang,X.Org.Lett.2012,14,1938.(c)Belhomme,M.-C.;Poisson,T.;Pannecouke,X.Org.Lett.2013,15,3428;(d)Taguchi,T.;Kitagawa,O.;Morikawa,T.;Nishiwaki,T.;Uehara,H.;Endo,H.;Kobayashi,Y.Tetrahedron Lett.1986,27,6103.(e)Sato,K.;Omote,M.;Ando,A.;Kumadaki,I.J.Fluorine Chem.2004,125,509.(f)Qiu,W.;Burton,D.J.Tetrahedron Lett.1996,37,2745.(g)Yokomatsu,T.;Murano,T.;Suemune,K.;Shibuya,S.Tetrahedron 1997,53,815.)在一定程度上解决了这类化合物合成的困难。但是,这些方法仍然存在诸如:官能团兼容性不好、催化剂用量高、反应条件苛刻等不足。
因此,探索一种高效简便、官能团兼容性好、催化剂用量低、反应条件温和合成α-芳基、杂芳基或烯基-α,α-二氟烯丙基结构化合物及其衍生物的方法具有显著的意义。
