Continuous glucose monitoring (CGM) is crucial in order to avoid complications caused by change in blood glucose for patients suffering from diabetes mellitus. The long-term consequences of high blood glucose levels include damage to the heart, eyes, kidneys, nerves and other organs, among others, caused by malign glycation of vital protein structures. Fluorescent monitors based on arylboronic ...

A new bidentate phosphoramidite (N-Me-BIPAM) based on Shibasaki's N-linked BINOL was synthesized. This ligand appears to be highly effective for rhodium-catalyzed asymmetric conjugated addition of arylboronic acids to α,β-unsaturated enones. The reaction of ortho-substituted arylboronic acid with acyclic and cyclic enones provides the corresponding products in good yields and enantioselectivities.

the cross-coupling reaction between phenylboronic acid and various types of aryl halides (suzuki reaction) was carried out using a catalytic amount of a new palladium catalyst (1-benzyl-3-(1-benzyl-1-methylpyrrolidin-1-ium-2-yl) pyridin-1-ium palladium chloride [dbnt][pdcl4]) in poly (ethylene glycol) (peg-200) in the presence of koh as the base. this new catalyst was synthesized and characteri...

The palladium-catalyzed conjugate addition (Michael addition) of ortho-substituted arylboronic acids to β,β-disubstituted cyclic enones, in particular 3-methyl cyclopent-2-enone and 3-methyl cyclohex-2-enone, is reported. With an achiral bipyridine-based palladium catalyst, good yields are obtained with a variety of ortho-substituted arylboronic acids. In the asymmetric version, good to very hi...

We report herein a metal-free cross-coupling of diazirines with arylboronic acids under oxidative conditions. The reaction affords a series of substituted olefins. It is proposed that the interaction between the nitrogen on diazirine with arylboronic acid plays a key role in this transformation.

Free NH 2-substituted 3-arylindoles have been prepared usually in good to high yields through the palladium-catalyzed reaction of readily available 2-alkynyltrifluoroacetanilides with arylboronic acids under oxidative conditions. The reaction tolerates a variety of useful functional groups both in the arylboronic acid and in the alkyne, including chloro, formyl, and ester groups.

A straightforward synthesis of phenols from aryl boronic acids has been demonstrated using benzoic acid as a catalyst. Variety arylboronic bearing electron rich and withdrawing substituents gave the respective in good yields.

Arylboronic acids were found to be efficient catalysts for the amidation reactions between carboxylic acids and amines. Theoretical calculations have been carried out to investigate the mechanism of this catalytic process. It is found that the formation of the acyloxyboronic acid intermediates from the carboxylic acid and the arylboronic acid is kinetically facile but thermodynamically unfavora...

The Petasis reaction is the multi-component reaction of a carbonyl compound, amine, and arylboronic acid to form an α-amino acid or a β-aminoalcohol. In this work, as the first analytical application of the Petasis reaction, a high-performance liquid chromatographic (HPLC) method with fluorescence detection was developed for determination of glyoxylic acid. The glyoxylic acid was derivatized wi...

We report here the one-pot synthesis of 1,2,3-triazoles of arylboronic acids in water. An efficient method has been developed for the synthesis of 1,2,3-triazoles via a one-pot reaction of an arylboronic acid with sodium azide in the presence of Cu(2)-β-CD (CD = Cyclodextrin) as a nanocatalyst in water followed by a click cyclization reaction with an alkyne at room temperature in air without an...
