Description
技术领域
本发明涉及一种合成吲哚类化合物的方法,属于有机合成领域。
背景技术
吲哚类化合物广泛应用于合成药物、农药和光电材料,其高效、低成本的合成方法具有重要的工业应用价值。目前工业上主要采用苯胺和乙二醇为原料合成吲哚,该方法存在反应温度高、使用的催化剂毒性较大、产物收率低等缺点(EP169436;WO8300691;US332838;CA150729)。吲哚类化合物也可通过邻位卤代的苯胺与末端炔,在过渡金属催化剂存在下发生偶联和环化反应得到(JOrg.Chem.2006,25,9403;Adv.Synth.Catal.2008,16,2498;Org.Biomol.Chem.2012,44,8835)。此外,以2-烯基苯胺为原料,通过光催化法也能合成吲哚类化合物(J.Am.Chem.Soc.2013,135,1823)。这些方法普遍存在着催化剂价格昂贵和产物中重金属残留问题,在工业生产中的应用受到很大限制。
本发明提供一种合成吲哚类化合物的新方法,该方法采用2-酰基-N,N-二取代苯胺为原料,在氮气保护下,加入一种碱,在溶剂中加热,即可以良好的产率得到吲哚类化合物。该方法原料易得、操作简便、反应时间短、反应产率高,对于吲哚类化合物的工业制备具有很高的实用价值。
发明内容
本发明的目的是提供一种合成吲哚类化合物的方法。
具体的技术方案如下:
采用式(II)所示的2-酰基-N,N-二取代苯胺为原料,在氮气保护下,加入一种碱,在溶剂中加热,得到式(I)所示的吲哚类化合物;所述的碱为叔丁醇钾、叔丁醇钠、叔丁醇锂、甲醇钠;所述的溶剂为二氧六环、二甲基亚砜、N,N-甲基甲酰胺、N,N二甲基乙酰胺;所述的式(I)和式(II)结构的化合物如下:

R3代表C1~C10烷基、苯基、甲基苯基、甲氧基苯基、氯代苯基、溴代苯基、苄基、甲氧基苄基、三氟甲基苄基、甲酰基、乙酰基、苯甲酰基;
R4代表苯基、甲基苯基、甲氧基苯基、三氟甲基苯基、氯代苯基、溴代苯基、萘基;
R3和R4也可与它们连接的碳原子和氮原子一起形成四氢异喹啉环,该环中的苯环上的碳原子可选择性的有单取代和双取代,取代基为甲氧基、甲基、氯、溴、三氟甲基。
优选地,所述的碱为叔丁醇钾。
优选地,所述的碱相对于式(II)所示的2-酰基-N,N-二取代苯胺的用量的摩尔比为3:1~0.2∶1,更优选为1.2∶1。
优选地,所述的溶剂为N,N-二甲基甲酰胺。
