Used primarily as a building block in organic synthesis, especially in the development of pharmaceuticals. Its strained ring system offers unique reactivity, making it valuable for constructing complex molecules. The amine group allows for easy incorporation into larger structures, particularly in drug discovery where spirocyclic scaffolds are of interest for their metabolic stability and three-dimensional complexity. Commonly employed in the synthesis of bioactive compounds, including potential central nervous system agents and enzyme inhibitors. Also utilized in medicinal chemistry research to explore structure-activity relationships in novel drug candidates.
