摘要

在钨催化烯丙基胺化的基础上，开发出了一种高区域选择性的烯丙基胺合成方法。该方案由市场上可买到的 W(CO)3(MeCN)3 和 4,4′-二叔丁基-2,2′-联吡啶催化，可在温和的条件下以中等至良好的产率形成合成上有用的支链烯丙基 N-芳基和 N-烷基胺，支链/线性比例大于 20:1。这种不含贵金属的催化系统补充了由 Ir 或 Rh 复合物催化的传统烯丙基胺化反应。

Tungsten-Catalyzed Regioselective Allylic Amination

A highly regioselective synthesis of allylic amines based on a tungsten-catalyzed allylic amination has been developed. This protocol, which is catalyzed by commercially available W(CO)₃(MeCN)₃ and 4,4′-di-tert-butyl-2,2′-bipyridine, permits the formation of synthetically useful branched allylic N-aryl- and N-alkylamines in moderate to good yields with a >20:1 branched/linear ratio under mild conditions. The noble-metal-free catalytic system complements conventional allylic aminations catalyzed by an Ir or Rh complex.
