Abstract Ring contraction of 2,4,6-triarylpyrylium perchlorates by use of sodium nitrite mediated by ionic liquid has been used as a new, direct, and environmentally benign method for synthesis of bioactive 2-aroylfuran and novel 3,5-diaroyl-4-arylisoxazole derivatives in excellent yields. The versatility of the approach enables rapid and simple access to these pharmaceutically important compounds
摘要 离子液体介导的亚硝酸钠对高氯酸2,4,6-三芳基吡啶鎓的环收缩反应已被用作合成生物活性2-芳酰基呋喃和新颖的3,5-二芳酰基-4的直接,环境友好的新方法。 -芳基异恶唑衍生物,收率优异。该方法的多功能性使得能够快速简便地获得这些药学上重要的化合物。通过简单过滤容易地从反应混合物中分离出产物。 图形概要
