Used as an intermediate in organic synthesis, particularly in pharmaceutical research for constructing complex molecules. Its reactive tosylate group allows for nucleophilic substitution reactions, enabling the introduction of the cyanocyclobutyl moiety into target compounds. The presence of the benzyloxy and nitrile functional groups offers opportunities for further transformations, such as deprotection, reduction, or cyclization reactions. Commonly employed in the development of bioactive molecules, including protease inhibitors and other therapeutic agents where constrained ring systems like cyclobutane are desired for conformational control.
