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
