Boronic Acids & Derivatives

Boronic acids and boronic acid derivatives are important in organic synthesis and medicinal chemistry because of their versatility as synthetic intermediates in the preparation of complex molecules. We are pleased to provide a comprehensive portfolio of boronic acids for use in reactions, such as the powerful carbon-carbon bond-forming Suzuki–Miyaura palladium catalyzed cross-coupling reaction, the Stille coupling, Sonogashira coupling, Chan–Lam coupling, Lieberskind–Strogl coupling, conjugate additions, homologations, and electrophilic allyl shifts.

Boronic acids are also used in biological applications, for example for the inhibition of serine proteases. The Raines group has conducted profound research on pendant boronic acids enhancing the cytosolic delivery of a protein toxin, by forming boronate esters with the 1,2- and 1,3-diols of saccharides, such as those that coat the surface of mammalian cells.
