制备方法与用途

应用

2-氯喹唑啉是一种有机中间体，可通过亚苯甲酰基脲制备。具体步骤是先合成2,4-二氯喹唑啉，再进行脱氯反应得到目标产物。

制备 2,4-二氯喹唑啉 (IIIA)

将2.0克亚苯甲酰基脲和0.6毫升N,N-二甲基苯胺加入到6毫升三氯氧磷中，在回流条件下反应7小时。冷却至室温后，减压除去大部分三氯氧磷，剩余液体转移至冰水中搅拌，产生大量土黄色固体。抽滤并用蒸馏水洗涤滤饼后干燥，得到1.6克黄绿色固体(IIIA)，产率为65%；熔点为118-119℃；1H-NMR (400 Hz, CDCl3) δ: 7.75-7.79(m, 1H), 8.02-8.03(m, 2H), 8.29(d, J=8.4Hz, 1H)。

2-氯喹唑啉 (IIIB)

将0.5克2,4-二氯喹唑啉(IIIA)、含9% NH4OH的饱和盐水10毫升和0.5克活化锌粉加入到装有10毫升二氯甲烷的茄型烧瓶中，在回流条件下反应4小时。冷却后，抽滤除去锌粉，减压蒸除溶剂，用乙酸乙酯萃取有机层。经干燥、过滤并减压蒸除溶剂后，通过柱层析分离得到0.2克2-氯喹唑啉(IIIB)，产率为40%。

  微波辅助合成喹啉，异喹啉，喹喔啉和喹唑啉衍生物作为CB2受体激动剂

  摘要：

  使用微波辅助合成法合成喹啉，异喹啉，喹喔啉和喹唑啉衍生物，并使用[ 35 S]GTPγS结合测定法测定其CB1 / CB2受体活性。大部分制备的喹啉，异喹啉和喹喔啉基苯胺均显示出低效的部分CB2受体激动剂活性。最有效的CB2配体是4-吗啉基甲酮衍生物（化合物40e）（-log EC 50  = 7.8；E max  = 75％）。异喹啉-1-基（3-三氟甲基-苯基）胺（化合物26c）是一种高效的CB2激动剂（-log EC 50  = 5.8; E max = 128％）。在这些研究中，没有发现明显的CB1受体激活或失活，除了40e表现出弱的CB1激动剂活性（CB1-log EC 50  = 5.0）。这些配体用作开发选择性CB2受体激动剂的新型模板。
