A highly efficient one-pot synthesis of 3-azidopiperidines has been achieved by an intramolecular cyclization of unsaturated amines that allows for the nucleophilic installation of an azide moiety. This method unlocks the versatile employment of the azide functionality in the preparation and biological studies of piperidine-containing structures. This strategy has been expanded for the direct incorporation
通过不饱和胺的分子内环化可以实现叠氮基部分的亲核安装,从而实现了3-叠氮基哌啶的高效一锅合成。该方法在含哌啶结构的制备和生物学研究中开启了叠氮化物功能的广泛应用。该策略已经扩展,可以直接掺入各种氮亲核试剂,因此可以快速,模块化地合成具有重要药物和生物学意义的3-氨基和3-amidopiperidines。特别值得注意的是,这种转化的区域选择性使得能够形成反马尔可夫尼科夫型加合物,从而补充了基于马尔可夫尼科夫的烯烃氨基官能化方法。
