Used as a chiral intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals where stereochemistry plays a critical role in drug efficacy. Its structure supports asymmetric synthesis, enabling the development of enantiomerically pure substances. Commonly applied in the preparation of protease inhibitors and other therapeutic agents requiring high stereoselectivity. The sulfinamide group acts as a directing and protecting group in complex multi-step reactions, facilitating selective transformations. Also utilized in medicinal chemistry research for building constrained peptidomimetic frameworks.
