Abstract
The synthesis of 2-(tetrazol-5-yl)-2 H-azirines is reported for the first time. Using the Neber approach, β-ketoxime-1 H-tetrazoles were converted into the target 2 H-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)-2 H-azirines.
