Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its boronic acid functionality enables Suzuki-Miyaura cross-coupling reactions, allowing for the formation of carbon-carbon bonds in complex molecule assembly. The protected azetidine ring provides a rigid, three-dimensional structure that can enhance binding selectivity and metabolic stability in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies and library diversification in drug discovery programs.
