azido-Ugi reactions was studied. It was shown that the reaction allows access to five-, six- and seven-membered perfluoroalkylated cyclic amines connected to a tetrazole ring. The scope and limitations of this approach are discussed. When benzyl isocyanide was used in the azido-Ugi reaction, it was shown that the tetrazole products could easily be debenzylated by catalytic hydrogenation to form 1H-tetrazoles
研究了全氟烷基化环亚胺在叠氮基-Ugi反应中的应用。结果表明,该反应允许获得与四唑环相连的五元、六元和七元全氟烷基化环胺。讨论了这种方法的范围和局限性。当在叠氮基-Ugi 反应中使用苄基异氰化物时,表明四唑产物可以很容易地通过催化氢化脱苄基,以优异的产率形成 1H-四唑。
