Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds. Its rigid spirocyclic structure makes it valuable for designing drugs targeting central nervous system disorders, including potential applications in antidepressants and antipsychotics. The nitrogen-containing ring system enhances binding selectivity to certain receptors, improving drug efficacy. Also explored in the development of novel kinase inhibitors and as a scaffold in medicinal chemistry for optimizing metabolic stability and solubility in new drug candidates.
