Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of antiviral and antidiabetic agents. Its diol structure with N-Boc protection and defined stereochemistry makes it valuable for constructing complex molecules where stereocontrol is critical. Commonly employed in asymmetric synthesis to introduce the pyrrolidine scaffold while preserving the (3R,4R) configuration. The tert-butyl carbamate (Boc) group allows for easy protection and deprotection of the nitrogen during multi-step syntheses, enhancing its utility in medicinal chemistry and process development.
