Biocatalysis Under Reduced Pressure; Two‐Step, One‐Pot Amide Synthesis Using an Immobilised Transaminase/Lipase Cascade in Combination With By‐Product Removal

open access: yesChemBioChem, Volume 27, Issue 6, 27 March 2026.
The application of biocatalytic cascades for organic synthesis can be encouraged through the use of easy‐to‐handle, immobilised enzymes and common laboratory equipment. We present a sequential biocatalytic cascade reaction that couples a transaminase (ATA) with a lipase, and achieves high conversion and enantioselectivity through by‐product removal ...

Selective Electrochemical sp3 CO Bond Hydrogenolysis: From Model Compounds to Lignin

open access: yesChemElectroChem, Volume 13, Issue 6, 17 March 2026.
Electrochemical sp3 CO bond cleavage is systematically investigated under constant‐current conditions using simple aryl ether models and extended to organosolv lignin. Controlled electron flow, regulated proton availability, and a sacrificial magnesium anode enable selective lignin depolymerization, yielding chemically distinct fractions with aromatic

Use of QSARs in international decision-making frameworks to predict ecologic effects and environmental fate of chemical substances [PDF]

open access: yes
This article is a review of the use, by regulatory agencies and authorities, of quantitative structure–activity relationships (QSARs) to predict ecologic effects and environmental fate of chemicals. For many years, the U.S.
