一类2-氮杂二环[4.2.0]辛烷化合物及其合成及应用
技术领域
本方法涉及2-氮杂二环[4.2.0]辛烷类化合物的合成及应用,尤其是一类具有潜在生物活性及药用价值的2-氮杂二环[4.2.0]辛烷类化合物的合成方法。
背景技术
四元环骨架常见于众多在生物、医药及工业领域有广泛应用的天然产物中。[2+2]环加成反应是制备四元环化合物的重要途径。在[2+2]环加成反应反应中,光催化是非常重要的一个手段,但不同波长区域的光在日光中含量不同,且有紫外区域的光具有较高能量,在具体试验中需要特殊反应设备及容易产生副反应,因此,利用日光中含量丰富的可见光进行[2+2]环加成反应具有重要意义,尤其在生物和医药领域有广阔的应用前景[a)Winkler,J.D.;Bowen,C.M.;Liotta,F.Chem.Rev.1995,95,2003;b)P.Margaretha,Helv.Chim.Acta2014,97,1027;c)Poplata,S.;

A.;Zou,Y.;Bach T.Chem.Rev.2016,116,9748.]。
目前,光催化[2+2]环加成反应多应用于分子内研究,而底物范围更为广阔的分子间[2+2]环加成反应报道较少,且这些已有分子间光催化[2+2]环加成反应实例具有如下缺陷:如原料自身易聚合,产物区域、立体选择性差等。
1971年,Evanega报道了异喹诺酮与大量过量(≥10倍摩尔量)的2,3-二甲基-2-丁烯,异丁烯,1,1-二氯乙烯在高压汞蒸气紫外灯照射6-9天产生异喹诺酮自身“头对头”二聚产物及相应[2+2]分子间1∶1环加成产物。该反应中当2,3-二甲基-2-丁烯或异丁烯参与反应时均有副产物异喹诺酮自身“头对头”二聚产物产生,产率(9-30%)。而当1,1-二氯乙烯参与反应时,有两种加成方式即“头对头”、“头对尾”产物产生,产率81%、19%。仅当异丁烯参与反应时,只有头对头方式加成产物生成,产率70%[Evanega,G.R.;Fabiny,D.L.Tetrahedron Lett.1971,12,1749]。1981年,Kankeo小组报道了类似反应:4-乙酰氧基或3-甲氧基-2甲基易奎宁-1(2H)-酮与极大过量烯烃发生“头对头”方式[2+2]环加成反应,产率54-96%,dr1∶1-1∶3。1985年,Kankeo小组报道了在350nm波长光照射30分钟,2-(ω-烷烯基)异奎宁酮发生分子内[2+2]环加成反应生成相应四元环产物,产率70-74%。此类产物长时间光照或在300nm波长光照下发生烯烃复分解反应生成副产物邻位烯丙基取代苯甲酰胺产物[Naito,T.;Kaneko,CTetrahedron Lett.1981,22,2671]。近年来,Bach小组发表了一系列异奎宁酮发生分子内[2+2]不对称环加成反应合成生物碱的工作[a)Bach,T.;Hehn,J.P.Angew.Chem.,Iht.Ed.2011,50,1000;b)Brimioulle,R.;Bach,T.Science2013,342,840;.c)Coote,S.C.;Bach,T.J.Am.Chem.Soc.2013,135,14948;d)Coote,S.C.;

1987年,Neier小组利用125W中压汞灯作为光源,实现了N-甲氧基羰基-5,6-二氢-4-吡啶酮与烯烃发生分子间[2+2]环加成反应,产率65-96%,dr1.5∶1-3∶1[a)Guerry,P.;Neier,R.Chimia1987,41,341;b)Guerry,P.;Neier,R.J.Chem.Soc.,Chem.Commun.1989,1727;c)Aeby,D.;Eichenberger,E.;Haselbach,E.;Suppan,P.;Guerry,P.;Neier,R..Photochem.Photobiol.1990,52,283;Guerry,P.;Blanco,P.;Brodbeck,H.;Pasteris,O.;Neier,R.Helv.Chim.Acta.1991,74,163.]Comins小组则利用该类反应合成了多种生物碱[a)Comins,D.L.;Zheng,X.J.Chem.Soc.,Chem.Commun.1994,2681;b)Comins,D.L.;Lee,Y.S.;Boyle,P.D.Tetrahedron Lett.1998,39,187;c)Comins,D.L.;Zhang,Y.-m.;Zheng,X.Chem.Commun.1998,2509;d)Comins,D.L.;Williams,A.L.Org.Lett.2001,3,3217;e)Comins,D.L.;Zheng,X.;Goehring,R.R.Org.Lett.2002,4,1611.]。
1985年,Adembri发现在低压汞灯照射下(λ≥365nm),N-苄基-1,4-二氢吡啶酰胺化合物与丙烯腈可发生[2+2]环加成反应[Adembri,G.;Camparini,A.;Donati,D.;Fusi,S.;Ponticelli,F.;Scotton,M.Heterocycles,1985,23,2885.],产率为64%,有四个非对映异构体产物,产物区域选择性低(2∶3)、立体选择性较差(de5%,de15%),此外产物不稳定不能直接分离得到[a)Adembri,G.;Camparini,A.;Donati,D.;Fusi,S.;Ponticelli,F.;Scotton,M.Tetrahedron Lett.,1983,24,5399;b)Adembri,G.;Camparini,A.;Donati,D.;Fusi,S.;Ponticelli,F.Heterocycles,1985,23,2885;c)Adembri,G.;Camparini,A.;Donati,D.;Fusi,S.;Ponticelli,F.VIConvegnoNaz.Chim.Farm.Alghero,14-18Ottobre1987,p.8]。
依据以上研究发现,2-氮杂二环[4.2.0]辛烷类化合物在医药、生物领域有巨大应用前景。而合成该类化合物较为直接的光催化[2+2]环加成方法存在以下缺陷如:1.需要高能紫外区域光源;2.底物局限于异奎宁酮、5,6-二氢-4-吡啶酮、缺电子烯烃;3.反应化学选择性、区域选择性及立体选择性差。上述合成上的不足使该类化合物在医药、生物领域没有被很好开发利用,因此发展可见光催化的高效高选择性合成2-氮杂二环[4.2.0]辛烷类化合物具有重大意义。
1,4-二氢吡啶作为还原型辅酶类似物自其合成以来就受到广泛关注。1,4-二氢吡啶是一类1,4-二氢吡啶(1,4-DHP)结构化合物,在生物体内可作为一类钙离子通道拮抗剂,并展现多种生物活性如抗菌,抗肿瘤抗艾滋等活性,已有多种此类结构药物如尼非地平、拉西地平等用于临床。此类药物通过对1,4-二氢吡啶结构进行修饰,改善了此类结构药物在生物体内吸收效果不好、溶解性差同时降低药物毒副作用,减少对生物体刺激。
因此,从本身原料易合成的且具有广泛医药研究价值的1,4-二氢吡啶[Rimoli,M.G.;Avallone,L.;Zanarone,S.;Abignente,E.;Mangoni,A.J.Heterocyclic Chem.,2002,39,1117]底物出发,去构建以往方法合成效率不高的2-氮杂二环[4.2.0]辛烷类化合物具有重大意义。
