Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules featuring an azetidine core. The aldehyde group enables further functionalization through reactions such as reductive amination or Wittig chemistry, allowing for the introduction of diverse side chains. The tert-butyl carbamate (Boc) group provides amine protection during multi-step syntheses, ensuring selective reactivity. Its thioether linkage adds stability and can influence pharmacokinetic properties in final drug candidates. Commonly employed in medicinal chemistry for constructing complex heterocyclic systems, with the azetidine ring enhancing cell permeability and target specificity.
