Chemistry – A European Journal, Volume 32, Issue 37, 1 October 2026.Quinolin‐4‐ones were converted to chloroquinolinium salts, allowing formation of axially chiral aminoquinolinium salts via an enantioretentive SNAr reaction with a variety of amine nucleophiles. The salts have a high rotational barrier, with a racemization half‐life of ∼1000s of years.

Chemical Metabolomics: Chemical Biology Tools for Advanced Metabolism Investigations
Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.The human metabolism has been investigated for several millennia. The metabolome is known for a high complexity due to a large number of different metabolites that are present at different concentrations. Metabolomics has been developed as a field to investigate the entire human metabolome and to elucidate disease development mechanisms.

Acridone studies. XIII. The nature of hexabromoacridone
, 1975 Acheson's ?hexabromoacridone?1 is shown to be 1,2,3,4,5,7-hexabromo-9- acridone by a combination of N.M.R. spectroscopy and synthesis from specifically tritiated 9-acridones. In boiling piperidine, the bromines at C 1 and C 3 are replaced.
