Palladium-Catalyzed Ortho-Arylation of O-Phenylcarbamates with Simple Arenes and Sodium Persulfate

, 2016
By palladium catalysis, the C−H bond functionalization of O-phenylcarbamates with simple arenes has been achieved using sodium persulfate (Na2S2O8), an inexpensive, easy-to-handle, and environmentally friendly oxidant.

Separation of enantiomers of chiral sulfoxides in high-performance liquid chromatography with cellulose-based chiral selectors using methanol and methanol-water mixtures as mobile phases [PDF]

, 2018
The interplay between structural details of chiral analytes and selectors in the separation of 14 chiral sulfoxides was systematically studied on 18 different polysaccharide-based chiral columns.

Benzyl 2-((E)-Tosyliminomethyl)phenylcarbamate

Molbank, 2016
Benzyl 2-((E)-tosyliminomethyl)penylcarbamate was prepared in good yield and characterized by the condensation reaction of benzyl 2-formylphenylcarbamate with p-toluenesulfonyl amine. The structure of the newly synthesized compound was determined using 1H, 13C-NMR, IR and mass spectral data.

How to Easily Depolymerize Polyurethane Foam Wastes by Superbase Catalysts in Ionic Liquids Below 100 °C

Angewandte Chemie, Volume 137, Issue 5, January 27, 2025.
A novel, sustainable, and scalable method for the efficient depolymerization of polyurethane foam waste is presented, employing ionic liquids and superbase catalysis as reaction media at 95–98 °C, and highlighting the potential for industrial application of the resulting polyol.

Amidase‐Catalyzed Desorption of CO2 Captured in Aqueous Monoethanolamine (MEA) Solutions

Angewandte Chemie International Edition, EarlyView.
CO2 is captured in aqueous monoethanolamine (MEA) sorbents as carbamate and bicarbonate/carbonate. The subsequent desorption for storage or utilization is energy‐intensive, and this is a major impediment to industrial carbon dioxide removal (CDR) processes. The desorption process can be promoted by enzymes that catalyze the dissociation of distinct CO2‐

Chiral (Stereoselective) Drugs, Asymmetric Synthesis, and Racemic Resolution Methods

Chirality, Volume 38, Issue 7, July 2026.
Chirality is crucial in drug development since both biological targets in the organism and the majority of pharmaceutical compounds are chiral. The synthesis and resolution of chiral compounds are critical steps while developing chiral drugs. Asymmetric synthesis and racemic resolution are the two most common methods for obtaining enantiopure drugs ...

Na+-coupled D-glucose uptake and membrane order of enterocyte brush border membrane vesicles, under the effect of a series of N-phenylcarbamates

, 1986
The importance of the hydrophobic effect of exogenous substances and of modifications of membrane order on D-glucose uptake are still poorly defined. Our results show that the concentrative Na+ -coupled D-glucose uptake of rat enterocyte brush border ...

Analysis of triacylglycerol and phospholipid sn‐positional isomers by liquid chromatographic and mass spectrometric methodologies

Mass Spectrometry Reviews, Volume 45, Issue 1, Page 4-36, January/February 2026.
Abstract Analysis of triacylglycerol (TG) and phospholipid sn‐positional isomers can be divided into two main categories: (a) direct separation by chromatography or other means such as ion mobility mass spectrometry and (b) quantification of regioisomer ratios by structurally informative fragment ions with mass spectrometric methods.
