DNA-Compatible Copper/TEMPO Oxidation for DNA-Encoded Libraries. [PDF]
Bioconjug Chem, 2023 Aldehydes are important synthons for DNA-encoded library (DEL) construction, but the development of a DNA-compatible method for the oxidation of alcohols to aldehydes remains a significant challenge in the field of DEL chemistry.

Cellulose oxidation by Laccase-TEMPO treatments [PDF]
Carbohydrate Polymers, 2017 In this work, laccase-TEMPO (Lac-T) treatments were applied to bleached commercial dissolving pulp in order to introduce carbonyl and carboxyl groups, which were found to improve dry and wet strength-related properties.

Effect of catalyst and oxidant concentrations in a TEMPO oxidation system on the production of cellulose nanofibers. [PDF]
RSC AdvIn traditional TEMPO oxidation systems, the high cost of TEMPO catalysts has been a significant barrier to the industrialization of oxidized CNF. From an economic perspective, presenting the characteristics of various CNFs produced with the oxidation ...

Chemical Recovery in TEMPO Oxidation
BioResources, 2016 The environmentally and economically friendly 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) oxidation process requires recycling and/or recovery of chemicals. In this work, hypochlorite recycling via electrolysis was evaluated and potential means for TEMPO recovery were explored.

Electrochemical TEMPO-Catalyzed Oxidative Ugi-Type Reaction [PDF]
ACS Organic & Inorganic Au, 2021 Oxidative isocyanide-based multicomponent reactions (oxidative IMCRs) are very useful tools for the rapid construction of molecular diversity starting from readily available and stable substrates. Despite all their benefits, such multicomponent reactions are underdeveloped and strictly limited to 3-component processes.

TEMPO/NaClO2/NaOCl oxidation of arabinoxylans
Carbohydrate Polymers, 2021 TEMPO-oxidation of neutral polysaccharides has been used to obtain polyuronides displaying improved functional properties. Although arabinoxylans (AX) from different sources may yield polyuronides with diverse properties due to their variable arabinose (Araf) substitution patterns, information of the TEMPO-oxidation of AX on its structure remains ...

TEMPO-Oxidized Cellulose with High Degree of Oxidation [PDF]
Polymers, 2017 In this paper, water-soluble 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose with a high degree of oxidation was prepared by a two-step process using bamboo dissolving pulp. The first step was to destroy the cellulose crystal I by NaOH/urea solution to obtain cellulose powder with decreased crystallinity.
