Boronic Acid‐Based Carbohydrate Sensing
Chemistry – An Asian Journal, 2015AbstractThe covalent boron–diol interaction enables elaborate design of boronic acid‐based saccharide sensors. Over the last decade, this research topic has been well developed thanks to the integration of boronic acid chemistry with a range of techniques, including supramolecular chemistry, materials chemistry, surface modification, and nanotechnology.

Alginate‐Boronic Acid: pH‐Triggered Bioinspired Glue for Hydrogel Assembly
Advanced Functional Materials, 2019The development of bioadhesives has become an emerging research field for tissue sealants, wound dressings, and hemostatic agents. However, assembling hydrogels using bioadhesive‐mediated attachment remains a challenging task.

Double Couplings of Dibromothiophenes Using Boronic Acids and Boronates
Synthesis, 2008One-pot double couplings of dibromothiophenes have been investigated. Standard Suzuki couplings work well for 2,4-dibromothiophene, but are much more sensitive to steric effects in the case of 2,3-dibromothiophene. By using the recently reported potassium borates, though, good yields for both dibromothiophene isomers can be achieved.

One-step fabrication of boronic-acid-functionalized carbon dots for the detection of sialic acid.
Talanta: The International Journal of Pure and Applied Analytical Chemistry, 2019Typically, sialic acids (SA) with a nine-carbon backbone are found at the glycan chain termini on the cell membranes, which play crucial roles in various physiological and pathological processes.

Boronic acid sensors with double recognition sites: a review.
In Analysis, 2019Boronic acids reversibly and covalently bind to Lewis bases and polyols, which facilitated the development of a large number of chemical sensors to recognize carbohydrates, catecholamines, ions, hydrogen peroxide, and so on.

Swapping boron acids for carbon acids
Science, 2017Organic Chemistry Carbon-bound boronic acids and their esters are widely used as coupling partners to make carbon-carbon bonds. More recently, these chemicals have garnered pharmaceutical interest in their own right. Li et al. report a versatile nickel-catalyzed process to replace carboxylic acids with boronate esters by using a phthalimide activator ...

Dihydropyrimidinones containing boronic acids
Canadian Journal of Chemistry, 2005The addition of formylphenylboronic acid derivatives to urea and ethyl acetoacetate proceeds in the absence of an additional Lewis acid catalyst to give the corresponding dihydropyrimidinones (Biginelli products) in good yields. Novel boron-containing dihydropyrimidinones have been investigated for their ability to act as anticancer agents against the

Australian Journal of Chemistry, 1965
The relative rates of iodinolysis of benzene-, thiophen-2-, and thiophen-3-boronic acids at 25° were found to be 1 : 700 : 104, or for thiophen-2- and thiophen-3-boronic acid 14 : 1. These values correlate reasonably well with data on protodetrimethylsilylation, and may be satisfactorily understood in terms of current molecular orbital theory.

Serum cholinesterase inhibition by boronic acid
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1984Horse serum cholinesterase (acylcholine acylhydrolase, EC 3.1.1.8) was reversibly inhibited by a variety of alkyl- and areneboronic acids with Ki values ranging from 6.2 mM (methaneboronic acid) to 3.1 microM (diphenylboric acid). Binding to the enzyme was apparently at the active center, because inhibition obeyed competitive kinetics and because ...
