5‐Hydroxymethylfurfural Derived Epoxy Monomers Reactions With COS: Synthesis of Polymeric Thiocarbonates with Pendant Aldehyde or Vinyl Groups

Macromolecular Rapid Communications, EarlyView.
A highly selective synthesis of an aldehyde‐functional polymonothiocarbonate (PMTC) was achieved through the copolymerization of a renewable‐sourced epoxide monomer and carbonyl sulfide. The epoxide monomer, derived from biomass‐based hydroxymethylfurfural (HMF) and epichlorohydrin (ECH), was produced in multigram quantities.

Electrokinetic Manipulations Combined With Direct and Ambient Ionization Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) is a powerful analytical technique that typically involves sample preparation and online analytical separation before MS detection. Traditional methods often face bottlenecks in sample preparation and analytical separation, despite the rapid detection capabilities of MS.

Reactivity of Imidazole‐ and Pyridine‐Carboxaldehydes for Gem‐Diol and Hemiacetal Generation: Theoretical and Experimental Insights

ChemistryOpen, EarlyView.
The generation of the gem‐diol and hemiacetal forms using pyridine‐ and imidazole‐carboxaldehyde isomers in different chemical environments was studied by NMR spectra and combined with theoretical calculations. Unlike aprotic solvents, protic ones, as water and methanol, favored the generation of the gem‐diol and hemiacetal structures.

On the Environmentally Friendly Synthesis of 2‐Hydroxyethyl Furan‐5‐Carboxylic Acid (MHEF) and bis(2‐Hydroxyethyl) Furan‐2,5‐Dicarboxylate (BHEF)

ChemistryOpen, EarlyView.
To better understand how the biocatalyzed depolymerization of polyesters works, model molecules are needed to develop activity assays and determine enzymatic kinetic parameters. In this communication the chemical synthesis and characterization of 2‐hydroxyethyl furan‐5‐carboxylic acid and bis(2‐hydroxyethyl) furan‐2,5‐dicarboxylates as potential model ...

One‐Step Aqueous Synthesis of Glycosyl Pyridinium Salts, Electrochemical Study, and Assessment of Utility as Precursors of Glycosyl Radicals Using Photoredox Catalysis

ChemistryOpen, EarlyView.
Unprotected glycosyl pyridinium salts may be accessed in a single step from the corresponding unprotected sugar in aqueous solution. Whilst meta‐ and para‐substitution is well tolerated, ortho substitution of the N‐heterocycle inhibits product formation. Electrochemical studies revealed reduction potentials in the range of −0.9 to −1.4 V.
