Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the preparation of antiviral and antidiabetic agents. Its protected alcohol and amine functionalities allow selective reactions in multi-step organic syntheses. The cyclopropyl and tert-butyl carbamate groups enhance stability and stereochemical integrity, making it valuable in asymmetric synthesis and drug development. Commonly employed in the production of β-amino alcohols and other bioactive molecules requiring high enantiomeric purity.
