NAD-dependent dehydrogenases enable efficient growth of Paracoccus denitrificans on the PET monomer ethylene glycol [PDF]

Nature Communications
Ethylene glycol is a monomer of the plastic polyethylene terephthalate (PET) and an environmental pollutant of increasing concern. Although it is generally accepted that bacteria use ethylene glycol as growth substrate, not all involved enzymes are well ...

Electrosynthesis of ethylene glycol from biomass glycerol [PDF]

Nature Communications
Ethylene glycol, a widely used chemical, has a large global capacity exceeding 40 million tons per year. Nevertheless, its production is heavily reliant on fossil fuels, resulting in substantial CO2 emissions.

Facile preparation of efficient Cu-SiO2 catalysts using a polyhydroxy molecular template to regulate surface copper species for dimethyl oxalate hydrogenation

Catalysis Communications, 2023
β-cyclodextrin (β-CD) was used to prepare remarkable and stable copper-based catalysts for hydrogenation of dimethyl oxalate (DMO) to ethylene glycol (EG). The DMO conversion (95.6% vs. 99.9%), EG selectivity (53.6% vs. 97.4%) and lifetime (25 h vs.

Access to enantioenriched compounds bearing challenging tetrasubstituted stereocenters via kinetic resolution of auxiliary adjacent alcohols

Nature Communications, 2021
A large number of enantiopure substances, such as those with tetrasubstituted carbon centres bearing several similar substituents, are inaccessible due to the incapability of chiral catalysts/ligands to recognize those substrates.

Radical Decarboxylative Carbon–Nitrogen Bond Formation

Molecules, 2023
The carbon–nitrogen bond is one of the most prevalent chemical bonds in natural and artificial molecules, as many naturally existing organic molecules, pharmaceuticals, agrochemicals, and functional materials contain at least one nitrogen atom.

Easy access to medium-sized lactones through metal carbene migratory insertion enabled 1,4-palladium shift

Nature Communications, 2020
Transannular construction of medium-sized lactones is entropically unfavoured. Herein, the authors describe a strategy for valuable medium-sized lactone synthesis from available benzaldehydes by selective C-H bond functionalization via palladium carbene ...

Asymmetric radical carboesterification of dienes

Nature Communications, 2021
Stereocontrol of C–O bond formation from a carbon-based radical is very difficult due to the rapid inversion of the carbon radical. Here the authors present a method to form chiral esters from conjugated dienes with copper and chiral PyBox ligands ...
