Description
技术领域
本发明涉及一种3,4-二氢异喹啉-1-酮及异吲哚啉-1-酮衍生物的合成新方法,属有机合成领域。
背景技术
二氢异喹啉-1-酮及异吲哚啉-1-酮类化合物广泛存在于多种天然产物和药物中,如抗焦虑药物帕秦克隆、促胃动力药物帕洛诺司琼、阿洛司琼及抗血栓药物阿哌沙班等。二氢异喹啉-1-酮及异吲哚啉-1-酮类化合物还是四氢异喹啉、异喹啉及异吲哚类化合物合成的重要前体。
目前,合成二氢异喹啉-1-酮的方法有:四氢异喹啉的氧化(Synlett,2011,1121);过渡金属催化的酰胺化合物与烯烃的分子间插入反应(J.Am.Chem.Soc.,2011,133,6449);异氰酸酯类化合物及胺基甲酸酯类化合物的分子内付-克酰基化反应(TetrahedronLett.,2015,56,3410;Chem.Eur.J.,2014,20,8682);过渡金属催化的CO对2-卤代芳基乙胺类化合物的分子间插入反应(J.Org.Chem.,2012,77,9313)。
目前,合成异吲哚啉-1-酮的方法有:过渡金属催化的CO对2-溴苄胺类化合物的分子间插入反应(J.Organomet.Chem.,1985,285,293);邻苯二甲酰亚胺的羰基的选择性还原反应(J.Heterocycl.Chem.,1978,15,369);邻醛基苯甲酸或者邻苯二甲醛与胺的分子间反应(J.Org.Chem.,1977,42,4217;Org.Lett.,2012,14,1876;Green Chem.,2012,14,3410);芳基卤代物与异氰酸酯的反应(J.Org.Chem.,2000,65,8108)。
上述方法存在使用过渡金属催化、需要特殊的或者不稳定的反应物、制备工艺比较复杂、反应条件苛刻等缺点。由于异喹啉及异吲哚衍生物结构的多样性,高效合成二氢异喹啉-1-酮及异吲哚啉-1-酮类化合物具有重要的工业应用价值。
本发明提供一种合成3,4-二氢异喹啉-1-酮及异吲哚啉-1-酮类化合物的新方法。该方法采用2-烯基苯甲酰胺为原料,在氮气保护下,加入一种碱,在溶剂中加热,即可以良好的收率得到3,4-二氢异喹啉-1-酮或异吲哚啉-1-酮类化合物。该方法操作简便、反应收率高、反应中无需使用过渡金属催化剂,对于3,4-二氢异喹啉-1-酮及异吲哚啉-1-酮类化合物的工业制备具有很高的应用价值。
