Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. The tert-butyl carbamate group serves as a protected amine, enabling selective reactions in multi-step organic syntheses. The cyclobutyl ketone moiety allows for further functionalization, such as nucleophilic addition or ring expansion reactions, making it valuable in constructing complex molecular frameworks. Commonly employed in medicinal chemistry for optimizing lead compounds and enhancing metabolic stability.
