Widely used in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura coupling, this compound serves as a valuable boronic ester reagent. Its spirocyclic structure and protected amine group make it ideal for constructing complex nitrogen-containing molecules, especially in pharmaceutical and agrochemical research. The tert-butyl carbamate (Boc) protection allows for selective deprotection under mild acidic conditions, enabling sequential functionalization in multi-step syntheses. The presence of the boronate ester group facilitates efficient carbon-carbon bond formation, making it a key building block in the development of bioactive compounds and heterocyclic scaffolds.
