The Mannich reaction has long been used by chemists for the synthesis of stereoselective synthesis of β-amino-carbonyl compounds. Here, the authors show a catalytic homo-Mannich reaction of cyclopropanols with in situ-formed imines, furnishing chiral 2,6-disubstituted piperidines in good yields with high diastereoselectivities due to the use of a diketiminate-complexed copper.]]>Nature Catalysis, Published online: 24 October 2025; doi:10.1038/s41929-025-01409-3
Darwinian evolution has shaped life on our planet through natural selection. Here, the authors report on the combination of self-replication, mutation and protometabolism in an out-of-equilibrium abiotic chemical system that can lead to natural selection for protometabolic activity.]]>Nature Catalysis, Published online: 24 October 2025; doi:10.1038/s41929-025-01420-8
Deuterated bioactive compounds are important as diagnostic tools and pharmaceuticals, but current methods of development are limited. Here the authors report how a silicon Lewis acid and a tertiary amine base act as a frustrated Lewis pair to catalyse the hydrogen exchange reaction for the deuteration of amides and esters.]]>Nature Catalysis, Published online: 24 October 2025; doi:10.1038/s41929-025-01433-3
Artificial photobiocatalytic reactions are appealing but sometimes suffer from non-enzymatic side reactions. Now a photoenzyme for enantioselective [2â+â2] photocycloaddition of 2-naphthyl derivatives is reported and combined with designed quenchers that shut down the competing enzyme-free racemic reaction.]]>Nature Catalysis, Published online: 23 October 2025; doi:10.1038/s41929-025-01425-3
Insights into the mechanism of methylthio-alkane reductase (MAR)âa nitrogenase-like enzyme essential for growth under sulfate-limited conditionsâhave remained scarce. Now a cryo-EM structure of MAR from Rhodospirillum rubrum, along with spectroscopic investigations, reveals how it uses complex metallocofactors for catalysis.]]>Nature Catalysis, Published online: 23 October 2025; doi:10.1038/s41929-025-01426-2
Methylthio-alkane reductases are recently discovered enzymes that can produce methanethiol and small hydrocarbons from methylated sulfur compounds. Now the cryo-EM structure of a methylthio-alkane reductase complex is solved, revealing large metalloclusters previously observed only within nitrogenases.]]>Nature Catalysis, Published online: 23 October 2025; doi:10.1038/s41929-025-01421-7
The structure and properties of the electric double layer that forms at the electrodeâelectrolyte interface is crucial in determining the performance of electrocatalytic reactions. This Perspective puts forward and discusses three major schools of thought on electrolyte effects and electrocatalyst design.]]>Nature Catalysis, Published online: 23 October 2025; doi:10.1038/s41929-025-01427-1
CO adsorption free energy has been suggested as a descriptor to explain and predict CO2 reduction activity across various electrocatalysts, but methods for determining it experimentally under operating conditions are lacking. Here a kinetic model is combined with rotating ring-disk voltammetry to estimate this parameter.]]>
