unsaturated hydrocarbons have been considered for allylic amination reactions to minimize waste production. Herein, we present an iridium-catalysed method for reductive allylic amination of α,β-unsaturated aldehydes with amines to afford N-allylic amines under air conditions. This protocol is demonstrated to provide products from many substrates (41 examples) in moderate-to-excellent yields. This synthetic
烯丙基胺化是构建广泛存在于生物活性分子中的N-烯丙基胺的有力工具。一般来说,烯丙醇和不饱和烃已被考虑用于烯丙胺化反应,以尽量减少废物的产生。在此,我们提出了一种铱催化的方法,用于在空气条件下将 α,β-不饱和醛与胺进行还原烯丙基胺化,得到N-烯丙基胺。该方案经证明可以从许多底物(41 个示例)中提供中等至优异产量的产品。这种合成方法还体现在药物分子、光学纯产品的合成以及放大实验上。
