Used as an intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex organic molecules, particularly in pharmaceutical and agrochemical research. The boronate ester group facilitates carbon-carbon bond formation under mild conditions, making it valuable for constructing functionalized azetidine derivatives. These derivatives are often explored as bioisosteres or rigid scaffolds in drug design, especially in the development of CNS-active compounds and protease inhibitors. Its tert-butyloxycarbonyl (Boc) and benzyl protecting groups allow for selective deprotection and further functionalization during multi-step syntheses.
