  • Phenols and their derivatives are ubiquitous in nature and important within the chemical industry. Their properties are linked to their substitution patterns, but meta-isomers are underrepresented due to the difficulty of their synthesis. Now we address this challenge by describing a 1,2-transposition of phenols that enables a formal para- to meta-isomerization.

  • Indole-5,6-quinone (IQ) is a long-sought intermediate and structural subunit of eumelanin pigments whose instability has precluded isolation and characterization. It has now been shown that a sterically shielded derivative of IQ exhibits hallmark eumelanin properties, including near-infrared absorption, ultrafast nonradiative decay and a persistent semiquinone radical formed by comproportionation.

  • Many biosynthetic cyclizations are catalysed by iron oxygenases and appear to involve long-lived radical species. Now, mimicking these biosynthetic transformations, the total synthesis of highly oxidized lignan natural products has been reported using redox-neutral photocatalysis to enable late-stage radical cyclizations that install challenging 5- and 11-membered rings.

  • Melanins are a diverse family of natural pigments with a unique combination of optical, electronic, redox, and structural properties that challenge conventional chemical characterisation. Here, the authors summarize insights from the first international interdisciplinary meeting dedicated to melanin and advocate for a unified approach to understanding melanin’s complex chemistry and advancing melanin-based technologies.
