Description
技术领域
本发明涉及有机化学领域,尤其涉及三氟甲基取代反式烯醇酯化合物的制备方法。
背景技术
烯醇酯作为一类重要的有机小分子砌块,被广泛应用于众多有机合成反应当中。如在羟 醛缩合反应(A.Yanagisawa,Y.Matsumoto,K.Asakawa,H.Yamamoto,J.Am.Chem.Soc.,1999, 121,892–893.)、曼尼希反应(N.Isambert,M.Cruz,M.J.Arevalo,E.Gomez,R.Lavilla,Org. Lett.,2007,9,4199–4202.)、不对称氢化反应((a)W.J.Tang,X.M.Zhang,Chem.Rev.,2003,103, 3029–3070.(b)G.Erre,S.Enthaler,K.Junge,S.Gladiali,M.Beller,Coord.Chem.Rev.,2008,252, 471–491.)、环化反应(H.Urabe,D.Suzuki,M.Sasaki,F.Sato,J.Am.Chem.Soc.,2003,125, 4036–4037.)、交叉偶联反应(B.M.Rosen,K.W.Quasdorf,D.A.Wilson,N.Zhang,A.M. Resmerita,N.K.Garg,V.Percec,Chem.Rev.,2011,111,1346–1416.)、多肽缩合反应(H. G.A.Strohmeier,M.Leypold,T.Nuijens,P.J.L.M.Quaedflieg,R.Breinbauer,Adv. Synth.Catal.,2013,355,1799–1807),甚至工业聚合反应(H.Arakawa,M.Aresta,J.N.Armor, M.A.Barteau,E.J.Beckman,A.T.Bell,J.E.Bercaw,C.Creutz,E.Dinjus,D.A.Dixon,K.

因此,烯醇酯类化合物的快速高效合成及其后期多样化修饰一直是有机化学家和药物化 学家的一个研究重点。过渡金属催化羧酸对炔烃化合物的加成,无疑成为烯醇酯类化合物合 成的最直接有效方法。由于其路线具有最高的原子经济性和结构可调的高化学选择性,高区 域选择性和高立体选择性,近年来为国内外有机化学界所广泛关注,并且成为一个新兴的研 究热点((a)F.Alonso,I.P.Beletskaya,M.Yus,Chem.Rev.,2004,104,3079–3159;(b)F.Luo,C.

三氟甲基在有机化学中是一个非常特殊的基团,其具有许多优异的物理化学性能,而且 普遍存在于许多新药物和新材料当中。由于氟元素在所有元素中电负性最大,而其原子半径 仅比最小的氢原子略大,具有特殊的代谢稳定性,亲脂性和疏水性,所以三氟甲基官能团往 往给这些新药和新材料带来特别的性能((a)M.Shimizu,T.Hiyama,Angew.Chem.Int.Ed., 2005,44,214–231;(b)M.Schlosser,Angew.Chem.Int.Ed.,2006,45,5432–5446;(c)K.Sato,A.

Tsuji,T.Itoh,Org.Lett.,2011,13,3285–3287.)。这种方法最大的不足是催化剂价格较高,膦配 体具有一定毒性,而且对空气敏感,容易被氧化,所以对实验操作有较高要求,也不适合大 规模工业化生产,限制了此方法的实际应用。基于以上两种已知方法的不足,迫切需要开发 新的生产工艺路线。
