Based on the literature review, it has been established that utilizing the nitrile group as a precursor of the methyleneamine component holds great promise for further research in sultam synthesis. Therefore, it is of interest and significance to explore the applicability of this method for the synthesis of spirocyclic sultams, where the nitrile group serves as a diatomic CN component in the formation of future heterocyclic systems. This approach opens up new avenues for the efficient synthesis of functionalized spirocyclic sultams with potential applications in various fields of chemistry and biology.
