Used primarily as an intermediate in pharmaceutical synthesis, this compound enables the formation of carbon-carbon bonds via Suzuki-Miyaura cross-coupling reactions. Its boronate ester group reacts selectively with aryl or vinyl halides in the presence of a palladium catalyst, making it valuable for constructing complex organic molecules. The protected azetidine ring allows for controlled functionalization in drug development, particularly in creating bioactive structures with improved metabolic stability. It is commonly employed in the synthesis of small-molecule therapeutics, especially in oncology and central nervous system research.
