Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of neuroactive compounds and central nervous system (CNS) therapeutics. Its rigid bicyclic structure and functional groups make it valuable for designing potent and selective receptor modulators. Commonly employed in the preparation of drug candidates targeting epilepsy, anxiety, and other neurological disorders due to its ability to mimic bioactive conformations of neurotransmitters. The tert-butyl protecting group facilitates controlled reactivity during multi-step synthesis, improving yield and purity in final active pharmaceutical ingredients (APIs).
