Strategies Toward Synthesis and Conversion of Lignin Model Compounds

open access: yesChemistry – A European Journal, EarlyView.
The conversion of lignin toward value‐added products relies on the cleavage of C─C and C─O bonding patterns, which has proven to be a difficult task previously, with numerous factors at play. The employment of model compounds which are fashioned on the structure and linkages found within lignin aids in the development of catalytic processes which can ...

The Synthesis of Aryl‐β‐C‐Glycosides from Native Saccharides

open access: yesChemistry – A European Journal, EarlyView.
Native mono‐, di‐, and trisaccharides are converted into p‐nitrophenol‐β‐C‐glycosides in a one‐pot reaction using water as the solvent. A sequence of condensation reactions is used to construct the aromatic ring from acyclic precursors. Using this approach, a modular synthesis of SGLT2‐inhibitor scaffolds was developed and applied to a novel protecting‐

Recyclable, Biobased Polycarbonates and Polyesters by Naphthoxy‐Imine Zinc and Magnesium Complexes

open access: yesChemistry – A European Journal, EarlyView.
Zinc and magnesium complexes, like skilled composers, craft polymeric symphonies by orchestrating diverse combinations of monomers. Once their performance is complete, the polymers gracefully can be decomposed back into their original monomers, ready to be composed into new symphonies. Abstract Naphthoxy‐imine pyridine zinc and magnesium complexes were

Influence of the Substitution Pattern of Terpene‐Based Seven‐Membered Lactones on Yttrium‐Mediated Ring‐Opening Polymerization: A Kinetic and Mechanistic Investigation

open access: yesChemistry – A European Journal, EarlyView.
(‐)‐Menthide and trans (+)‐carvomenthide, differing only in substitution pattern, were polymerized via ROP using a bis(phenolate) yttrium catalyst. Kinetic studies showed faster polymerization of (+)‐carvomenthide but greater control with (‐)‐menthide. Experimental and DFT analyses revealed mechanistic differences in chain propagation, highlighting how

Ameliorative effects of D-glucuronolactone on oxidative stress and inflammatory/fibrogenic responses in livers of thioacetamide-treated rats

open access: yesJournal of Functional Foods, 2015
D-Glucuronolactone (C6H8O6, lactone), naturally found in plant gums, is commercially acclaimed for its hepatoprotective effects. This study was to investigate whether lactone can attenuate thioacetamide (TAA)-induced liver fibrosis in a rat model ...
