Structure-Reactivity Relationships in Boronic Acid-Diol Complexation.

ABSTRACT: Boronic acids have found widespread use in the field of biomaterials, primarily through their ability to bind with biologically relevant 1,2- and 1,3-diols, including saccharides and peptidoglycans, or with polyols to prepare hydrogels with dynamic covalent or responsive behavior. Despite a wide range of boronic acid architectures that have been previously considered, there is a need for greater understanding of the structure-reactivity relationships that govern binding affinity to diols. In this study, various boronic acids and other organoboron compounds were investigated to determine their pK _a and their binding constants with the biologically relevant diols including sorbitol, fructose, and glucose. Boronic acid pK _a values were determined through sp
