The diastereoselective conjugate addition of secondary homoallylamines, obtained in the enantioenriched form via allylmetallation of imines, to α,β-unsaturated esters is reported. This method allows access to valuable building blocks as well as heterocyclic skeletons, providing tertiary amines bearing two chains integrating a stereogenic center adjacent to the nitrogen atom.
据报道,通过亚胺的烯丙基金属化以对映体富集的形式将仲高烯丙基胺非对映选择性共轭加成到α,β-不饱和酯上。该方法允许获得有价值的结构单元以及杂环骨架,从而提供带有两条链的叔胺,这些链整合了与氮原子相邻的立体中心。
