Description
技术领域
本发明属于有机合成领域,具体涉及一种3-酰基喹啉类化合物的合成方法。
背景技术
喹啉类衍生物具有抗疟疾、抗结核、抗肿瘤、抗高血压、抗炎、杀菌等药理活性,被广泛用于医药行业,是很多重要的药物中间体。经研究表明,喹啉上引入各种不同的官能团,可能会有不同的药用价值。在众多的喹啉衍生物中,3-酰基喹啉及其衍生物是新颖的对羟苯基丙酮酸双加氧酶抑制剂,并常用于药物、天然产物以及材料等的合成中,显示出广阔的应用前景。
现有合成3-酰基喹啉类化合物的一种方法是采用氯化钌和醋酸催化苯并[c]异噁唑和烯胺酮缩合而成。这种方法使用重金属作为催化剂,污染较大不利于绿色环保。另一种方法是在DMSO溶液中加入过硫酸钾,苯甲醛和苯并[c]异噁唑缩合而成或者在DMSO中加入苯胺,烯胺酮,过硫酸钾缩合。这两种方法收率不高,且后处理较为不便。还有一种方法是在DMSO溶剂中加入对甲苯磺酸,苯胺和烯胺酮缩合。该方法同样收率较低且底物适用范围较窄。另外还有在DMSO中加入苯胺,烯胺酮,过硫酸钾缩合。因此,采用廉价易得的原料,高效催化剂参与反应和开发对环境友好高效的绿色合成路径具有很重要的意义,而且合成3-酰基喹啉化合物的方法是有迫切需求的。
