conventional two-step methods. Nonoxidative and noncoupling reaction conditions have been developed for the synthesis of N-(diphenylmethyl)- and N-(1-adamantyl)amide derivatives directly from aldehydes by employing the concept of a Schmidt and Ritter reaction sequence in a one-pot operation. The reagent mixture consisting of sodium azide and HBF4·OEt2 in acetic acid converts the aldehydes into their respective
摘要 通过在一锅操作中使用施密特和里特反应序列的概念,已经开发了直接从醛合成N-(二苯基甲基)-和N-(1-金刚烷基)酰胺衍生物的非氧化和非偶联反应条件。由叠氮化钠和HBF 4 ·OEt 2在乙酸中组成的试剂混合物将醛转化为各自的腈类似物,然后与二苯甲醇或1-金刚烷醇进行Ritter反应,得到相应的N-(二苯基甲基)-或N-(1-金刚烷基)酰胺衍生物,收率很高。该方法不需要柱色谱纯化即可分离出产物。由于其简单的反应过程和简便的产物纯化技术,该方法优于早期的常规两步法。 通过在一锅操作中使用施密特和里特反应序列的概念,已经开发了直接从醛合成N-(二苯基甲基)-和N-(1-金刚烷基)酰胺衍生物的非氧化和非偶联反应条件。由叠氮化钠和HBF 4 ·OEt 2在乙酸中组成的试剂混合物将醛转化为各自的腈类似物,然后与二苯甲醇或1-金刚烷醇进行Ritter反应,得到相应的N-(二苯基甲基)-或N
