Dibenzyl-(1S*,2S*)-2,3-dihydro-1H-indene-1,2-dicarboxylate

open access: yesMolbank, 2023
The synthesis of dibenzyl-(1S*,2S*)-2,3-dihydro-1H-indene-1,2-dicarboxylate has been realized through a diastereospecific bis-alkoxycarbonylation reaction, which starts from the cheap and easily available 1H-indene, benzyl alcohol, and carbon monoxide ...

Reactive carbonyl compounds related uremic toxicity (“carbonyl stress”)

open access: yesKidney International, 2001
Many studies on uremic toxins have focused on enzymatic biochemistry. Recently, attention has turned to nonenzymatic biochemistry, especially progressive and irreversible modifications of proteins. Two different approaches opened the field of irreversible nonenzymatic modifications of proteins in uremia: the advanced glycation end products (AGEs ...

Carboxylated Carbon Nanotube‐Supported Copper‐Indium Bimetallic Catalysts for Electroreduction of CO2 to Dimethyl Carbonate via Membrane‐Free Cascade Electrosynthesis

open access: yesCarbon and Hydrogen, EarlyView.
A membrane‐free cascade electrocatalytic system with Cu100In50‐(COOH)CNTs converts CO2 to CO and then couples with alcohols to yield DMC (52.3% FE) and DEC (27.8% FE) via carboxyl‐Cu‐In synergistic regulation of intermediate adsorption. ABSTRACT Under the background of the dual carbon strategy, upgrading CO2 electroreduction from C1 products to high ...
