We obtained a 47% yield. We also measured the X-ray crystal structure. This derivative has a relatively low boronic acid pKa value of 7.8 when acetylated or attached to acrylamide hydrogels. It also contains a pendant amine which facilitates attachment to polymers, for example. We are using this compound to construct glucose sensing materials that operates at the physiological pH of bodily fluids. © 2003 Published by Elsevier Ltd.
