The preparation of allylic amines is traditionally accomplished by reactions of amines with reactive electrophiles, such as allylic halides, sulfonates, or oxyphosphonium species; such methods involve hazardous reagents, generate stoichiometric waste streams, and often suffer from side reactions (such as overalkylation). We report here the first broad‐scope nickel‐catalysed direct amination of allyl alcohols: An inexpensive Ni^II/Zn couple enables the allylation of primary, secondary, and electron‐deficient amines without the need for glove‐box techniques. Under mild conditions, primary and secondary aliphatic amines react smoothly with a range of allyl alcohols, giving secondary and tertiary amines efficiently. This “totally catalytic” method can also be applied to electron‐deficient nitrogen nucleophiles; the practicality of the process was demonstrated in an efficient, gram‐scale preparation of the calcium antagonist drug substance flunarizine (Sibelium®).

简单，广泛范围的镍（0）预催化剂体系，可直接胺化烯丙醇

传统上，烯丙基胺的制备是通过胺与反应性亲电试剂，例如烯丙基卤化物，磺酸盐或氧phosph物种的反应来完成的。这样的方法涉及危险试剂，产生化学计量的废物流，并且经常遭受副反应（例如烷基化过度）。我们在这里报告了第一项广谱镍催化的烯丙醇直接胺化反应：一种廉价的Ni ^II/ Zn对可实现伯胺，仲胺和电子不足的胺的烯丙基化，而无需使用手套箱技术。在温和的条件下，伯和仲脂族胺与一系列烯丙醇均能平稳反应，从而有效地生成仲和叔胺。这种“完全催化”的方法也可以应用于缺电子的氮亲核试剂。该方法的实用性在高效，克级的钙拮抗剂药物氟那利嗪（Sibelium®）的制备中得到了证明。
