Used in Suzuki-Miyaura cross-coupling reactions as a stable and easily handled boron reagent. Its main advantage lies in the MIDA (N-methyliminodiacetic acid) protecting group, which enhances stability toward purification and storage while allowing controlled release of the active boronic acid under mild aqueous conditions. This makes it especially useful in iterative cross-coupling strategies for building complex organic molecules, including natural products and pharmaceuticals. The ester’s stability also enables compatibility with a wide range of functional groups and reaction conditions, improving selectivity and yield in multi-step syntheses.
