Oxidative Folding of a Two‐Chain Protein Having Three Interchain Disulfide Bonds. Synthesis of Bromelain Inhibitor VI Through Native Chain Assembly

Chemistry – A European Journal, EarlyView.
Bromelain inhibitor VI, a two‐chain protein stabilized by three interchain SS bonds and two intrachain SS bonds, was synthesized in an incredibly high isolated yield (53%) just by mixing the two native chains in a buffer solution. This success made a record of oxidative protein folding for the most complicated and difficult one.

Photocatalysis Enables Chemodivergent Radical Polar Crossover: Ritter‐Type Amidation vs Heck‐Type Olefin Carbofunctionalizations

Chemistry – A European Journal, EarlyView.
One aryl makes the difference: switching styrenes with 1,1‐diaryl olefins as radical acceptors, the benzylic cation intermediate fate changes from Ritter‐type carboamidation to Heck‐type reaction. The decarboxylative photocatalytic chemodivergent methodology enabled broad scope and efficient scalability in both batch and flow.

Advances in Mechanochemical Methods for One‐Pot Multistep Organic Synthesis

Chemistry – A European Journal, EarlyView.
This review highlights recent advances in mechanochemical methods for multistep organic synthesis, focusing on sequential one‐pot approaches performed by grinding or ball milling. The presented transformations are discussed in terms of efficiency, applicability, and sustainability, assessing both the challenges and potential of solvent‐free one‐pot ...
