Description

一种具有苄位季碳中心的苯并环衍生物的制备方法
技术领域
本发明涉及一种具有苄位季碳中心的苯并环衍生物以及一种具有治疗癌痛及手术后疼痛的药物氢溴酸依他佐辛的制备方法,属于有机合成和药物化学领域。
背景技术
具有苄位季碳中心的1,2,3,4-四氢化萘或1,2-二氢化茚结构骨架是一类重要的结构单元,广泛存在于具有生物活性的天然产物和医药试剂中([1]D.M.Roll,P.J.Scheuer,J.Am.Chem.Soc.1983,105,6177.[2]P.W.Brian,J.C.McGowan,Nature 1945,156,144;[3]J.MacMillan,A.E.Vanstone,S.K.Yeboah,Chem.Commun.1968,613;c)J.R.Hanson,Nat.Prod.Rep.1995,12,381.[4]C.A.L.Bercht,J.P.C.M.Van Dongen,W.Heerma,R.J.J.C.Lousberg,F.J.E.M.Küppers,Tetrahedron 1976,32,2939.[5]L.Garrido,E.ZubHa,M.J.Ortega,J.Salva,J.Org.Chem.2003,68,293.[6]S.Shiotani,T.Kometani,K.Mitsuhashi,T.Nozawa,A.Kurobe,O.Futsukaichi,J.Med.Chem.1976,19,803.[7]P.W.Smethurst,W.H.Forrest,J.Hayden,Br.J.Anaesth.1971,43,1129.)。例如,具有1,2,3,4-四氢化萘结构的镇痛药物氢溴酸依他佐辛。目前,合成1,2,3,4-四氢化萘和1,2-二氢化茚化合物的方法主要有:(1)芳香化合物分子内的付克烷基化反应([1]D.Basavaiah,M.Bakthadoss,G.J.Reddy,Synthesis 2001,919;[2]Kurteva,V.B.;Santos,A.G.;Afonso,C.A.M.Org.Biomol.Chem.2004,2,514.);(2)过渡金属如铑催化的环加成反应(K.Tanaka,Y.Sawada,Y.Aida,M.Thammathevo,R.Tanaka,H.Sagae,Y.Otake,Tetrahedron 2010,66,1563);(3)过渡金属如金催化的环异构化反应([1]C.M.Grisé,Louis Barriault,Org.Lett.2006,8,905;[2]C.M.Grisé,Eric M.Rodrigue,LouisBarriault,Tetrahedron2008,64,797);(4)分子内的Heck反应([1]T.Takemoto,M.Sodeoka,H.Sasai,M.Shibasaki,J.Am.Chem.Soc.1993,115,8477;[2]G.Hirai,Y.Koizumi,S.M.Moharram,H.Oguri,M.Hirama,Org.Lett.2002,4,1627;[3]S.Kesavan,J.S.Panek,J.A.Porco,Org.Lett.2007,9,5203);(5)自由基环化反应([1]C.-W.Kuo,J.-M.Fang,Synthetic Communications,2006,31,877;[2]W.Kong,N.Fuentes,A.Garca-Domnguez,E.Merino,C.Nevado,Angew.Chem.Int.Ed.2015,54,2487)。然而,这些方法大多需要预先合成特殊的官能团,极大地限制了这些方法的使用范围。因此发展高效、简洁的合成新方法显得尤为重要。本发明以芳基碘化物与烷基溴化物或烷基碘化物为起始原料,在催化剂、配体、降冰片烯衍生物、碱的作用下,在30℃到120℃下于有机溶剂中搅拌反应,即得到具有苄位全碳季碳中心的1,2,3,4-四氢化萘和1,2-二氢化茚化合物。该方法所用的原料廉价易得,反应条件温和,底物普适性好,产率高,制备过程简单。
临床药物氢溴酸依他佐辛,具有治疗癌痛及手术后疼痛的作用,现有的报道方法中需要7到20步才能完成合成([1]S.Shiotani,T.Kometani,K.Mitsuhashi,T.Nozawa,A.Kurobe,O.Futsukaichi,J.Med.Chem.1976,19,803;[2]T.Takemoto,M.Sodeoka,H.Sasai,M.Shibasaki,J.Am.Chem.Soc.1993,115,8477;[3]A.N.Hulme,S.S.Henry,A.I.Meyers,J.Org.Chem.1995,60,1265;[4]S.Shiotani,H.Okada,T.Yamamoto,K.Nakamata,J.Adachi,H.Nakamoto,Heterocycles 1996,43,113;[5]A.Fadel,P.Arzel,Tetrahedron:Asymmetry 1997,8,371;[6]S.K.Taylor,M.Ivanovic,L.J.Simons,M.M.Davis,Tetrahedron:Asymmetry 2003,14,743;[7]Y.Nakao,S.Ebata,A.Yada,T.Hiyama,M.Ikawa,S.Ogoshi,J.Am.Chem.Soc.2008,130,12874;[8]Q.Chen,X.Huo,Z.Yang,X.She,Chem.Asian J.2012,7,2543),合成路线较长,效率低下。
