Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents. Its spirocyclic structure provides structural rigidity, making it valuable in drug design for enhancing selectivity and metabolic stability. Commonly employed in the preparation of novel receptor ligands, including those targeting neurological disorders. Also utilized in the creation of libraries for high-throughput screening due to its favorable solubility and stereochemical properties.
