Phenylboronic acidSolid phase extractionHypercrosslinked polymers (HCPs) have demonstrated effective adsorption capabilities because of their rich porosity and high specific surface area. However, the HCPs prepared with phenylboronic acid based compounds as monomers via Friedel-Crafts alkylation reaction have...
The conventional synthetic routes for cyanophenylboronic acids, either starting from carboxyphenylboronic acid via the formation of the acid amide with subsequent formation of the cyano compound or starting from the correspondingly substituted bromobenzonitrile by reaction with organolithium compounds, such ...

4-Mercaptophenylboronic acid derivatives were prepared by a metallation/boration sequence from S-protected 4-bromothiophenols; the t-butyldimethylsilylthioether was found suitable to allow subsequent regeneration of the mercapto group after boration. The parent compound, 4-mercaptophenylboronic acid, ...

glucose.37–40 Temperature-responsive hydrogels with phenylboronic acids underwent abrupt volume changes in response to the concentration of glucose due to the formation of a complex between phenylboronic acid and glucose, which induced an low critical solution temperature shift of the hydrogel networks...
Phenylboronic acid and its derivatives are typical glucose-responsive compounds and could specifically react with glucose [14]. Glucose oxidase is the Glucose-responsive insulin delivery systems Based on the discussion of the two challenges, it is promising to fabricate smart insulin delivery systems ...
Herein, single crystals of a covalent organic nanoribbon (named CityU‐27) are prepared through the assembly of hexahydroxytriphenylene (HHTP), 4,4′‐vinylenedipyridine (BYE), and phenylboronic acid (BA) together through dative boron←nitrogen (B←N) bonds. The single‐crystal X‐ray ...
linkage and pH-responsive between chlorinated catechol and phenylboronic acid [177]. The results showed that the hydrogel exhibited good antibacterial activity against gram-positive bacteria and gram-negative bacteria including MRSA under acidic conditions. On the contrary, under alkaline conditions, the ...
AN IMPROVED PROCESS FOR THE PREPARATION OF BORONIC ACID ESTERSThe present invention relates to an improved process for the preparation of a compound of formula (I), wherein PG1 may be independently selected from tert-butyloxycarbonyl (Boc), phthaloyl, 9-fluorenylmethyloxycarbonyl (Fmoc), ...
