Used in organic synthesis as a key reagent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds. Its vinylboronic acid structure allows for the introduction of cyclopentylvinyl groups into aromatic or heteroaromatic systems, which is valuable in the development of pharmaceuticals and agrochemicals. The (E)-configuration ensures stereochemical control in the resulting olefin products, making it useful in the synthesis of complex molecules where specific geometry is required. Also employed in medicinal chemistry for building blocks in drug discovery due to its stability and reactivity profile.
