Rhodium‐Catalyzed Regioselective Addition of N‐Hydroxyl Imides to Internal Alkynes

Israel Journal of Chemistry, Volume 66, Issue 3, May 2026.
An intermolecular rhodium‐catalyzed regioselective addition of N‐hydroxyl imides to internal alkynes leads to branched O‐allyl compounds, which can be readily transformed to allylic alcohols and O‐allyl hydroxylamines after deprotection. Isotopic labelling experiments suggest a plausible reaction mechanism.

Effect of pork carnosine level on lipid and protein oxidation markers during in vitro co‐digestion in a Mediterranean meal model

Journal of the Science of Food and Agriculture, Volume 106, Issue 7, Page 4008-4016, May 2026.
Abstract BACKGROUND This study assessed the effects of dietary carnosine during the in vitro digestion of a healthy meal model based on the Mediterranean diet, comprising lean pork enriched with two levels of carnosine, whole grain bread, tomato, onion, and olive oil.

Metal‐Free, Chemoselective Reduction of Aromatic Nitro Compounds in Water at Room Temperature

ChemistryOpen, Volume 15, Issue 5, May 2026.
A metal‐free, rapid, and chemoselective nitro reduction of aromatic compounds is developed using tetrahydroxydiboron as reducing agent and 4,4′‐bipyridine as organocatalyst. This green method provides an efficient entry to aromatic amines with high functional group tolerance in excellent yields under mild conditions using water as solvent. A metal‐free,

Structures of variants of Escherichia coli flavodiiron‐type nitric oxide reductase reveal changes in the di‐iron site

Acta Crystallographica Section D, Volume 82, Issue 5, Page 457-470, May 2026.
Flavodiiron proteins (FDPs) are di‐iron enzymes that reduce NO and/or O2 with distinct substrate selectivity. We have produced E. coli FDP variants targeting second coordination‐sphere residues and determined their structures. Although the kinetics remained unchanged, the E.

Photoinduced Selective Construction of Densely Functionalized Spirocyclic Ethers With Carbyne Equivalents

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
A reactivity programmed cascade between carbyne equivalents and allylic benzoates was developed that sequentially orchestrates all three reactivity modes of carbyne equivalents, enabling the rapid installation of three σ‐bonds at a single carbon center and providing efficient, scalable access to structurally diverse spirocyclic ethers. ABSTRACT Carbyne
