Abstract
本发明公开了一种4位喹喔啉基取代的醇类衍生物的合成方法。所述合成方法为:在适量银盐催化剂、氧化剂及质子酸添加剂存在的情况下,长链脂肪醇类化合物与喹喔啉类化合物偶联得到4位喹喔啉基取代的醇类衍生物。本发明具有原料廉价易得、工艺简单、反应条件温和、环境友好、产品纯度及收率高等优点。
Description
技术领域
本发明涉及一种在银盐做催化剂的条件下4位喹喔啉基取代的醇类衍生物的合成方法,具体为在氧化剂及质子酸添加剂存在情况下,用一定量的银盐催化反应物进行反应,合成4位喹喔啉基取代的醇类衍生物。
背景技术
醇类化合物及其衍生物在化学、药学、能源等领域都有广泛的应用。并且醇类化合物作为重要的药物中间体,其羟基可以进一步转化为卤素、醛基、羧基等官能团,为醇的多样化应用提供重要合成方法。
喹喔啉及其衍生物是一类重要的苯并吡嗪类杂环化合物,具有广泛的生物活性,可用作抗肿瘤剂、HIV-1逆转录酶抑制剂、NMDA受体拮抗剂、植物生长调节剂、杀菌剂、杀虫剂、除草剂、荧光探针以及染料中间体等诸多领域,如治疗丙肝的药物格拉瑞韦(Grazoprevir),伏西瑞韦(Voxilaprevir)和格卡瑞韦(glecaprevir)都含喹喔啉结构。
因此,如何有效的将容易且能大量获得的脂肪醇类化合物和喹喔啉类化合物进行有效的结合成了研究热点。
