This compound is primarily used in organic synthesis as a chiral building block for the preparation of more complex molecules. It is particularly valuable in the pharmaceutical industry for the development of enantiomerically pure drugs, as the (R)-configuration provides specific stereochemistry required for biological activity. It is often employed in the synthesis of ligands, catalysts, and intermediates for asymmetric reactions. Additionally, its Boc-protected amine group allows for selective deprotection, enabling further functionalization in multi-step synthetic processes. Its diphenyl structure contributes to steric hindrance, which can be advantageous in controlling reaction pathways and enhancing selectivity.
