Description

一种多取代喹喔啉衍生物及其制备方法
技术领域
本发明属于有机合成技术领域,具体涉及一种多取代喹喔啉衍生物及其制备方法。
背景技术
多取代喹喔啉具有杀菌、消炎、抗病毒、抗血栓降血糖、抗癌、抗抑郁等多种重要的生物活性,广泛应用于天然产物、医药、农药等领域。因此,多取代喹喔啉化合物及其类似物的新合成方法研究具有重要的运用价值,受到相关领域科研工作者的关注。
传统多取代喹喔啉合成方法主要是苯的邻位双取代类化合物和含有两个C的合成子之间的缩合反应,如邻苯二胺类化合物与1,2-二羰基化合物、α-羟基酮、α,β-二醇、α-溴代酮、炔烃、环氧化合物等的反应。近几年,过渡金属催化的串联反应合成喹喔啉化合物引起了有机合成化学家们的关注。但传统合成路线往往存在反应步骤多、反应条件苛刻、原料不易得、区域选择性差等问题。过渡金属催化的合成路线在一定程度上解决了传统合成路线反应步骤多、区域选择性差的问题,然而由于引入了金属,后处理过程中又增加了金属除去步骤。基于喹喔啉类化合物的结构多样性及其在医药、农药、工业上的广泛应用,开发新的合成方法研究具有深远的意义。
