Description
技术领域
本发明涉及一种喹啉衍生物的制备方法。
背景技术
喹啉类衍生物是一种具有重要生物活性的生物碱,可以作为精细化工产品的重要中间体, 在医药、食品、农药、日用化学品、涂料、纺织、印染、造纸、感光材料、高分子材料等领域有着广泛的用途,参见(J. Med. Chem. 2003, 46, 1242; J. Med.Chem. 2004, 47, 1617, Nat. Prod. Rep. 2007, 24, 223; Nat. Prod. Rep. 2005, 22, 627; Nature, 1998, 392, 289.)。其中的例子是溶血药物有氨基喹啉类(如伯氨喹等),该药物的母核骨架就是喹啉。还有比如2,4-二芳基喹啉TMC207能治疗多重耐药结核病,参见(N Engl J Med 2009; 360: 2397-405,June 4, 2009)。
通过Skraup方法合成喹啉衍生物是最经典的, 最近有文献报道了铁、铜和金等催化剂能催化醛、胺和端炔制备2,4-二取代喹啉衍生物,参见(Chem. Eur. J. 2009, 15, 6332; Tetrahedron, 2008, 64, 2755;J. Org. Chem. 2009, 74, 5476)。这些方法都涉及金属离子催化。由于取代喹啉衍生物的拥有较高的生物活性,而且经常能作为有机合成的重要中间体,因此进一步开发喹啉衍生物的高效的制备方法,对新药筛选等有重要意义。
发明内容
本发明的目的是提供一种反应温和、操作简便的制备喹啉衍生物的方法。
喹啉衍生物的制备方法,其制备过程是以芳香胺、醛和炔烃为原料,以碘为催化剂,在硝基甲烷中回流反应8~15小时,经过纯化过程得到喹啉衍生物,所说的芳香胺、醛、炔烃和碘之间的摩尔比为1:1:1~1.5:0.05~0.2;
反应式为:
式中:R1选自H、卤素、C1~C4的烃基、C1~C4的烃氧基、芳基或取代的芳基, R2选自C1~C8的烃基、酯基、苄基、芳基或取代的芳基,R3选自C4~C8的烃基、芳基或取代的芳基,所述取代的芳基上的取代基是H、卤素、C1~C4的烃基或C1~C4的烃氧基。
本发明与已有的合成方法相比,具有以下优点:
1)反应条件温和;
2)反应通用性强;
3)投料和后处理都非常简单;
4) 不需要金属催化,采用碘催化能兼容更多的取代基。
反应机理图如下:
