Used as a chiral intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals where stereochemistry plays a critical role. The silyl protecting group enhances stability during multi-step reactions, while the amide functionality allows for further derivatization. Commonly employed in the preparation of protease inhibitors and other therapeutic agents requiring high enantiomeric purity. Its protected alcohol group can be selectively deprotected to enable coupling reactions, making it valuable in asymmetric synthesis and medicinal chemistry research.
