六氢苯并喹啉-6-酮和六氢苯并吲哚-5-酮化合物、合成方法 及用途
技术领域
本发明涉及一种六氢苯并喹啉-6-酮和六氢苯并吲哚-5-酮化合物、合成方法及用途，具体地，本发明提供了一类天然产物Mesembrine的衍生物，所述的衍生物具有潜在的生物及医药应用前途。
背景技术
酚类化合物广泛的存在于自然界中并且是廉价易得的化学合成原料。近年来对于酚类化合物的去芳构化反应迅速发展起来，便捷的构建了环状烯酮结构，这些结构是一些天然产物以及生物活性分子的基本骨架。其中，利用金属钯催化的芳基化去芳构反应具有成键高效，产物结构多样的特点。已有的一些报道通过分子内底物设计，构建复杂的产物骨架。然而金属钯催化的分子间芳基化去芳构化反应更具挑战，已知的报道仅有一例[Xu,R.-Q.；Yang,P.；Tu,H.-F.；Wang,S.-G.；You,S.-L.Angew.Chem.Int.Ed.2016,55,15137.]。主要原因是分子间反应相对于分子内反应具有更加激烈的傅克芳基化以及醚化等副反应。在这一领域中，我们发展了金属钯催化的1-萘酚衍生物与芳基卤化物的分子间芳基化去芳构化串联Michael加成反应。有效的避免了傅克芳基化以及醚化等副反应。并且该反应可以高效的构建含氮杂环化合物，如六氢苯并喹啉-6-酮和六氢苯并吲哚-5-酮化合物。含氮化合物存在于大量的具有生物活性的天然产物和药物分子中[(a)Cordell,G.A.The alkaloid；Academic Press:New York,1998.Vol.51.(b)Pelmutter,P.Conjugate AdditionReactions in Organic Synthesis；Pergamon:Oxford,1992.(c)Kibayashi,C.Chem.Pharm.Bull.2005,53,1375.(d)Naito,T.Chem.Pharm.Bull.2008,56,1367.]。尤为重要的是该类六氢苯并喹啉-6-酮和六氢苯并吲哚-5-酮是天然产物(-)-Mesembrine的衍生物。(-)-Mesembrine。该类化合物是从Sceletium tortuosum分离得到的主要生物碱成分，具有显著的生理活性，如抑制血清素再摄入[Gericke,N.P.；VanWyk,B.-E.PCTInt.Appl.,WO 9746234CAN 128:80030,1997.]。其衍生物也很有可能具有多样的生物活性。因而高效便捷的合成该类生物碱的衍生物，对于药物化学或是有机合成化学都具有重要意义。

实施例4mesembrane衍生物的生物活性测试
松叶菊碱(mesembrine)属于番杏科生物碱，由Bodendorf等于1957年从番杏科日中花属植物Mesembryanthemum Tortuosum中首次分离得到。它是血清素再吸收抑制剂(Ki＝1.4nM)，还具有磷酸二酯酶4(PDE4)弱抑制作用。具有抗焦虑活性、抗成瘾性以及抗抑郁等生理活性。
采用文献报道的方法(Harvey,A.L.；Young,L.C.；Viljoen,A.M.；Gericke,N.P.(October 2011)."Pharmacological actions of the South African medicinal andfunctional food plant Sceletium tortuosum and its principal alkaloids".Journal of Ethnopharmacology.137(3):1124–1129.doi:10.1016/j.jep.2011.07.035.PMID21798331)，通过对本发明各个化合物进行血清素再吸收活性测试和PDE4抑制活性测试，结果显示，本发明各化合物具有与松叶菊碱类似的血清素再吸收活性和PDE4抑制活性。
