A Riboflavin‐Derived Flavinium Salt Mediates Chemoselective Methylation Reactions

open access: yesChemistry – A European Journal, Volume 32, Issue 5, 2 February 2026.
A two‐component methylation protocol was developed, where the active flavin mediator can be recycled in a single step. Crystallographic data and NMR spectroscopy support the mechanistic proposal, while chemoselective methylation was observed for a broad range of biologically relevant substrates. ABSTRACT Selective methylation is among the most relevant

Seasonality Affects the Phenolic Composition and Erythroprotective Activity of Ora‐Pro‐Nobis (Pereskia aculeata) Leaves

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
ABSTRACT Ora‐pro‐nobis (OPN) is a food plant with polyphenol‐rich leaves. However, the influence of seasonality on their quantitative phenolic composition and how it impacts their bioactivities is unknown. OPN leaves were harvested throughout 12 months, and their individual phenolic content, antioxidant activity, and erythroprotection were assessed ...
