Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex organic molecules, particularly in pharmaceutical development. Its boronate ester group facilitates carbon-carbon bond formation under mild conditions, making it valuable in constructing azetidine-containing drug candidates. The tert-butyloxycarbonyl (Boc) protecting group ensures stability during reactions and can be easily removed later in the synthesis. Commonly applied in medicinal chemistry for developing bioactive compounds with improved metabolic stability and binding affinity.
