Sugar-sweetened carbonated soft drinks (CSDs) are broadly consumed worldwide. The added sugar, particularly high-fructose corn syrup (HFCS), can be an important source of sugar degradation products, such as α-dicarbonyl compounds. This study recorded the α-dicarbonyl profile in CSDs by ultrahigh-performance liquid chromatography with hyphenated diode array-tandem mass spectrometry after derivat...

easily synthesized1-methyl-3-(2-oxyethyl)-1h-imidazol-3-ium-borate sulfonic acid {[moei]-bsa} as a novel catalyst efficiently promoted the synthesis of quinoxaline derivatives via condensation of various diamines with 1,2-dicarbonyl compounds at room temperature conditions in ethanol. this research provides a new method for the synthesis of quinoxalines in good to excellent yields with little c...

Iron (III) phosphate catalyzed condensation reaction of aldehydes, 1,3-dicarbonyl compounds and amuniom acetate refluxing ethanol that remains a common theme in current literature.

Correction for ‘Electrochemically-mediated C–H functionalization of allenes and 1,3-dicarbonyl compounds to construct tetrasubstituted furans’ by Mu-Xue He et al. , Org. Chem. Front. 2022, DOI: 10.1039/d1qo01458g.

The dual activation of simple substrates by the combination of organocatalysis and palladium catalysis has been successfully applied in a variety of different asymmetric transformations. Thus, the asymmetric a-allylation of carbonyl compounds, a-fluorination of acyl derivatives, decarboxylative protonation of β-dicarbonyl compounds, cyclization reactions of alkynyl carbonyl compounds and β-func...

a sequential process strategy was introduced for the synthesis of 2,3,4,5-tetrasubstituted pyrroles by the formation of benzoin from the corresponding aromatic aldehyde and followed by condensation reaction with 1,3-dicarbonyl compounds and ammonium acetate in the presence of diethylene glycol-bis(3-methylimidazolium) dihydroxide as catalyst in refluxing ethanol. the recycled catalyst could be ...

The selective nitrosation of β-dicarbonyl compounds with sodium nitrite was carried out under1-methyl-3-carboxymethylimidazolium chloride, prepared from N-methylimidazole andchloroacetic acid, as an acidic ionic liquid. The reaction was found to proceed under relativelymild conditions with excellent conversion and selectivity. The ionic liquid was recycled andreused.

This study investigated the stability of dicarbonyl compounds (DCs), 3-deoxyglucosone (3-DG), glyoxal (GO) and methylglyoxal (MGO) during simulated gastrointestinal digestion processes impact these have on gut microbiota. DCs pass almost unaltered through in-vitro phases (concentration loss: 11% for 3-DG, 24% GO MGO) an effect fermentative process, reducing total bacterial population up to 6 Lo...
