We describe a convenient and operationally simple protocol to prepare nicotinonitriles fused to either a cycloalkane or a saturated heterocycle, containing diverse substituents at position 2 of the nicotinonitrile core, under microwave irradiation. The protocol is useful for rapid and automated synthesis of the target compounds. An unusual case of the loss of a tert-butyl group is observed when tert-butylamine
我们描述了在微波辐射下制备与环烷烃或饱和杂环融合的烟腈的便捷且操作简单的协议,该环烷或烟碱在烟腈芯的位置2包含多个取代基。该协议可用于快速自动合成目标化合物。当使用叔丁胺引起吡啶环形成时,观察到叔丁基丢失的异常情况。
