2-Bromopyridines as Versatile Synthons for Heteroarylated 2-Pyridones via Ru(II)-Mediated Domino C–O/C–N/C–C Bond Formation Reactions

open access: yesMolecules
A novel methodology for the synthesis of 2-pyridones bearing a 2-pyridyl group on nitrogen and carbon atoms, starting from 2-bromopyridines, was developed employing a simple Ru(II)–KOPiv–Na2CO3 catalytic system.

Systemic Toxicity of L‐Mimosine in Rabbits: A Non‐Rodent Model for Safety Assessment

open access: yesJournal of Applied Toxicology, Volume 46, Issue 2, Page 639-651, February 2026.
ABSTRACT L‐mimosine is a non‐protein amino acid primarily found in the Mimosoideae subfamily, with high concentrations in Leucaena leucocephala and Mimosa pudica. These plants are widely used in both human and animal nutrition, as well as in phytotherapeutic applications. While the toxic effects of L‐mimosine have been extensively studied in ruminants,

Dichlorido[1-(1,10-phenanthrolin-2-yl)-2-pyridone]cadmium(II)

open access: yesActa Crystallographica Section E, 2008
In the title mononuclear complex, [CdCl2(C17H11N3O)], the CdII ion assumes a distorted trigonal–bipyramidal coordination geometry. The pyridone plane is twisted out of the 1,10-phenanthroline mean plane by 43.8 (3)°.

Asymmetric Homogeneous Hydrogenation of 2-Pyridones [PDF]

open access: yesSynlett, 2015
An asymmetric homogeneous hydrogenation of 2(1H)-pyridones has been developed, using a ruthenium complex bearing two chiral N-heterocyclic carbene (NHC) ligands. To the best of our knowledge, the presented reaction is the first example of a homogeneous asymmetric conversion of 2-pyridones into the corresponding enantioenriched 2-piperidones.

A study of the effects of exercise on the urinary metabolome using normalisation to individual metabolic output [PDF]

open access: yes, 2015
Aerobic exercise, in spite of its multi-organ benefit and potent effect on the metabolome, has yet to be investigated comprehensively via an untargeted metabolomics technology.

Tosvinyl and besvinyl as protecting groups of imides, azinones, nucleosides, sultams, and lactams. Catalytic conjugate additions to tosylacetylene. [PDF]

open access: yes, 2015
The use of the 2-(4-methylphenylsulfonyl)ethenyl (tosvinyl, Tsv) group for the protection of the NH group of a series of imides, azinones (including AZT), inosines, and cyclic sulfonamides has been examined.

Nickel‐Catalyzed cine‐Substitution Toward Carbonyl Dance

open access: yesChemistry – An Asian Journal, Volume 21, Issue 1, January 2026.
A nickel‐catalyzed cine‐substitution enables a 1,2‐carbonyl translocation (“carbonyl dance”) at tetralone derivatives under mild conditions. This transformation proceeds through enolization and selective amination, followed by hydrolysis, to afford β‐tetralones bearing migrated carbonyl groups.

An overview of synthesis and biological activities of 2-pyridone derivatives over the last decade

open access: yesDiscover Applied Sciences
2-Pyridone frameworks are a pervasive member of the N-heterocyclic family of both chemical and therapeutic interest. 2-Pyridones and their bridged analogues have wide occurrences in nature and the presence of both aromatic and amide groups in the ...
