The synthesis of 2-(tetrazol-5-yl)-2H-azirines is reported for the first time. Using the Neber approach, β-ketoxime-1H-tetrazoles were converted into the target 2H-azirines bearing phenyl, furan-2-yl, thiophen-2-yl, or pyrrol-2-yl substituents at C-3. It was demonstrated that the alkaloid-mediated Neber reaction allows the asymmetric synthesis of 2-(tetrazol-5-yl)-2H-azirines.
首次报道了2-(四唑-5-基)-2 H-叠氮基的合成。使用Neber方法,将β-酮肟-1 H-四唑转化为在C-3上带有苯基,呋喃-2-基,噻吩-2-基或吡咯-2-基取代基的目标2 H-叠氮基。它证实了生物碱-介导的反应Neber允许2-(四唑-5-基)的不对称合成-2 ħ -azirines。
