The addition of nucleophiles to CN bonds offers a highly efficient synthetic strategy for accessing nitrogen‐containing molecules.1 Among the well‐developed addition reactions, such as the highly efficient Mannich reaction, various CH bond‐activated compounds including carboxylic acid derivatives, nitroalkanes, and terminal alkynes have been applied as nucleophiles to achieve different classes of
在CN键上添加亲核试剂为获取含氮分子提供了一种高效的合成策略。1在发达的加成反应(例如高效的曼尼希反应)中,各种CH键活化的化合物(包括羧酸衍生物,硝基烷烃和末端炔烃)已被用作亲核试剂,以实现不同类别的胺。2然而,在使用金属催化剂时,使用不具有活化CH键的新亲核试剂(例如内部炔烃和烯丙酸酯)受到限制。3在此,我们希望报告通过银催化的炔丙酸酯的1,3迁移引发的烯丙基酯新加入C allN键的过程。
