Used in pharmaceutical synthesis as a protected intermediate, particularly in the development of kinase inhibitors and other bioactive molecules. The tert-butyl carbamate (Boc) group provides amine protection during peptide or heterocycle assembly, while the dimethoxyphosphoryl moiety allows for further functionalization via Horner-Wadsworth-Emmons olefination or phosphorylation reactions. Its structure supports the construction of complex drug candidates requiring selective reactivity and stability under multi-step synthesis conditions. Commonly employed in medicinal chemistry for optimizing metabolic stability and target binding affinity.
