邻位二胺是在生物活性分子中发现的常见基序。烯丙基胺衍生物的氢胺化反应是合成取代1,2-二胺的有效途径。在本文中,呈现了使用不同的胺亲核试剂(包括伯胺、仲胺、无环胺和环状脂肪胺)的铑催化的伯烯丙基胺和仲烯丙基胺的加氢胺化,以获得宽范围的不对称邻位二胺。通过快速合成几种甲基化的生物活性分子,进一步证明了这种方法的实用性。
Vicinal diamines are a common motif found in biologically active molecules. The hydroamination of allyl amine derivatives is a powerful approach for the synthesis of substituted 1,2-diamines. Herein, the rhodium-catalyzed hydroamination of primary and secondary allylic amines using diverse amine nucleophiles, including primary, secondary, acyclic, and cyclic aliphatic amines to access a wide range of unsymmetrical vicinal diamines is presented. The utility of this methodology is further demonstrated through the rapid synthesis of several methylated bioactive molecules.
