A method based on hydroamination mediated by inorganic base was developed for the synthesis of cyclic nitrones from alkenyl oximes. DFT calculations of the reaction pathway suggested that this hydroamination could proceed through an unprecedented nucleophilic amination of the unactivated alkene by the oxime nitrogen atom. The transition state of this reaction is stabilized by an ionic interaction between
开发了一种基于无机碱介导的加氢胺化的方法,用于从烯基肟合成环硝酮。DFT对反应途径的计算表明,这种加氢胺化反应可以通过肟氮原子对未活化烯烃进行前所未有的亲核胺化反应来进行。该反应的过渡态通过金属阳离子(例如K +)与肟氧和带负电荷的烯烃部分之间的离子相互作用而得以稳定。
