Used as a protected amine intermediate in organic synthesis, particularly in pharmaceutical and agrochemical development. Its strained spirocyclic structure enables unique reactivity in ring-opening and cycloaddition reactions, facilitating the construction of complex cyclic frameworks. The tert-butoxycarbonyl (Boc) group allows for selective protection of the amine, enabling multi-step synthesis with controlled deprotection under mild acidic conditions. This compound is valuable in medicinal chemistry for building constrained analogs that enhance metabolic stability and target selectivity.
