Chemistry – A European Journal, EarlyView.Cystine is unique among amino acids, in that the disulfide bond can allow intramolecular peptide bond formation. This cyclization offers potential advantages for intramolecular coupling selectivity in prebiotic peptide formation. ABSTRACT Treatment of cystine (the disulfide‐linked dimer of cysteine) with carbonyl sulfide (COS) results in the formation ...

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

A Green Protocol for the Deprotection of ortho‐Nitrobenzyl Esters and Ethers by UVA–LED Irradiation
Chemistry – A European Journal, EarlyView.This study presents a green and efficient photochemical protocol for the deprotection of ortho‐nitrobenzyl esters or ethers under mild conditions, using UVA‐LED irradiation in methanol. The broad applicability of the protocol was validated in the synthesis of a cytosolic phospholipase A2 inhibitor. ABSTRACT The removal of protecting groups in synthetic

Navigating the Radical Oxo‐Functionalization of Alkenes Toward Ketones
European Journal of Organic Chemistry, EarlyView.Straightforward access to complex ketones in a single synthetic step: This Review surveys the latest advances in three‐component alkene 1,2‐oxo‐functionalizations. The opportunities unlocked by the so‐called single‐electron (1e–) logic, including access to a broad pool of radical precursors and carbonyl oxygen atom sources, are highlighted.
