專利名稱:四氫喹啉類化合物及用路易斯酸催化的合成方法
技術領域:
本發(fā)明是使用一種路易斯酸催化醛,胺和亞甲基環(huán)丙烷的雜Diels-Alder反應,得到一種新穎的2,4-多芳基取代-3,1’-環(huán)丙基取代的四氫喹啉類衍生物。
背景技術:
N-雜環(huán)化合物由于其在藥物化學、材料化學、有機合成化學和顏料方面的重要應用而越來越受到人們的重視。這其中1,2,3,4-四氫喹啉類化合物由于其獨特的生物活性而備受人們的關注。如今已有成百種不管是簡單取代還是復雜取代的四氫喹啉類化合物被發(fā)現(xiàn)具有一定的生物活性,而且有一些還被發(fā)現(xiàn)具有一定的藥理活性[Katrizky,A.R.;Rachwal,S.;Rachwal,B.Tetrahedron,1996,52,15031-15070 and references cited therein.]。
天然化合物的化學修飾由于可能形成更高生物活性或具有不同的藥學性質(zhì)而越來越受到化學家們的青睞。大量的天然產(chǎn)物都含有三元環(huán)的結(jié)構(gòu),比如一些萜烯類化合物[Barluenga,J.; -Pérez,M.;Wuerth,K.;Rodríguez,F(xiàn).; F.J.Org.Lett.2003,5,905.],信息激素[(a)Müller,D.G.;Schmid,C.E.Biol.Chem.Hoppe-Seyler 1988,369,647.(b)Pohnert,G.;Bolard,W.Tetrahedron 1996,52,10037.],脂肪酸的代謝物[(a)Bao,X.-M.;Katz,S.;Pollard,M.;Ohlrogge,J.B.Proc.Natl.Acad.Sci.U.S.A.2002,99,7172.(b)Bao,X.-M.;Thelen,J.J.;Bonaventure,G.;Ohlrogge,J.B.J.Biol.Chem.2003,278,12846.],氨基酸[(a)Kordes,M.;Winsel,H.;de Meijere,A.Eur.J.Org.Chem.2000,3235.(b)Moye-Sherman,D.;Jin,S.;Li,S.-M.;Welch,M.B.;Reibenspies,J.;Burgess,K.Chem.Eur.J.1999,5,2730.(c)Martín- M.;Muray,E.;Aguado,G.P.;Alvarez-Larena,A.;Branchadell,V.;Minguillón,C.;Giralt,E.; R.M.TetrahedronAsymmetry.2000,3569.(d)Illescas,B.;Rifé,J.; R.M.;Martín,N.J.Org.Chem.2000,65,6246.(e)Ntzel,M.W.;Tamm,M.;Labahn,T.;Noltemeyer,M.;Es-sayed,M.;de Meijere,A.J.Org.Chem.2000,65,3850.]等等。而化合物中三元環(huán)的高張力性被認為是有可能誘導促使提高化合物或者其代謝物的活性。一些含有三元環(huán)的天然產(chǎn)物也越來越多的被化學家們合成利用[Donaldson W.A.Tetrahedron 2001,57,8589 andreferences cited therein.]。
由于上述的原因,現(xiàn)今已有大量的合成四氫喹啉類化合物的方法在文獻中被報導,比如Skraup反應[(a)Skraup,Z.H.Monatsh.Chem.1880,1,316;1881,2,139.(b)Manske,R.H.F.;Kulka,M.Org.React.1953,7,59.],F(xiàn)riedlander反應[Friedlander,P.Chem.Ber.1882,15,2572.],Pfitzinger反應[Pfitzinger,W.J.Prakt.Chem.1886,33,100.],等等[Elderfield,R.C.Heterocyclic Compounds,Ed.;Vol.4,Wiley,New York,1952.]。
利用亞胺與烯烴的雜Diels-Alder反應來合成四氫喹啉類化合物的方法由于其原子經(jīng)濟性也日益受到關注[Buonora,P.;Olsen,J.C.;Oh,T.Tetrahedron 2001,57,6099.]。但是文獻中報導此類反應對于底物的選擇局限性非常大,那就是反應中使用的烯烴必須為富電子烯烴,這樣就限制了底物的進一步拓展。而且文獻中有關芳香取代的四氫喹啉類化合物的合成方法報導得也非常有限,Kobayashi曾經(jīng)有兩例合成2,4-雙芳基取代四氫喹嚀類衍生物的報導,以較好的收率得到相應的產(chǎn)物[(a)Kobayashi,S.et al.J.Am.Chem.Soc.1996,118,8977.(b)Kobayashi,S.J.Org.Chem.1992,57,1842.]。
