C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

Chemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

Trends and Future Directions in Organic Chemistry for Drug Discovery

Chemistry – A European Journal, EarlyView.
Organic synthesis is being reshaped by the convergence of catalytic innovation, automation, artificial intelligence, and emerging therapeutic modalities. Late‐stage functionalization, photoredox and electrochemical methods, biocatalysis, flow chemistry, DELs, and proximity‐based drugs are examined as components of closed‐loop discovery.

Cyclic Disulfide Sorting Influenced by Subtle Steric and Electronic Effects

Chemistry – A European Journal, EarlyView.
The self‐assembly of two unsymmetrical dithiols to form cyclic disulfides are examined with an eye to the longitudinal equilibration behavior and directing agent effects on product distributions. Cyclic disulfide formation occurs in under 2 min, with full equilibration requiring up to 1 week.

Reversible Humidity‐Induced Vapochromism of a Cu(II) Tetramine Complex Driven by Iodide Access

Chemistry – A European Journal, EarlyView.
A humidity‐responsive Cu(II) vapochromic complex based on reversible iodide coordination is reported. Unlike the chloride and bromide analogues, [Cu(chxn)2(H2O)2]I2 exhibits rapid and reversible color changes with humidity. Spectroscopic, diffraction, ESR, and DFT studies reveal that dehydration induces axial iodide coordination to form [Cu(chxn)2I2 ...

Total Synthesis and Absolute Configuration of the Irregular Tetraterpene Viaticene A

Chemistry – A European Journal, EarlyView.
Viaticenes are tetraterpenes with a unique [6+2]‐connectivity from the springtail Hypogastrura viatica. Here, we report a modular 13‐step total synthesis of viaticene A, featuring stereoselective double‐bond formation, a Cu‐mediated allylic substitution, and Ni/Co‐cocatalyzed vinyl‐alkyl cross‐electrophile coupling as key steps.

A lumped modelling framework for the epoxidation of vegetable oils and fatty acid methyl esters

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Epoxidized vegetable oils and fatty acid methyl esters are promising bio‐based alternatives to phthalates for plasticizer applications. Their synthesis typically involves the reaction of unsaturated double bonds with peracetic acid in a biphasic liquid–liquid system, where the simultaneous occurrence of reaction and phase partitioning makes ...
