Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance

Chemistry – A European Journal, Volume 32, Issue 19, 22 May 2026.
This review covers the application of the bifunctional approach to photocatalysis as a means to attain (enhanced) enantioselectivity, and, more in general, as a strategy to enhance the catalytic performance through an effective use of short‐lived reaction intermediates.

Sustainable Syntheses of p‐Hydroxycinnamic‐Based Macrobisphenols: Progress, Challenges, and Comparative Assessment of Yield and Sustainability

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
The strengths and limitations of sustainable routes to macrobisphenols — safe‐by‐design biomass‐derived bisphenols — were critically evaluated to support informed selection based on sustainability metrics (EcoScale, E‐factor), efficiency, cost, and scalability.

Cedrela fissilis Vell. Inner Bark: LC–MS/MS‐Based Chemical Profiling and Toxicological Effects

Chemistry &Biodiversity, Volume 23, Issue 5, May 2026.
ABSTRACT Investigating the mechanistic toxicity of plant extracts is essential for safety assessment. The predictive toxicological effects of Cedrela fissilis were evaluated, and LC–MS/MS‐based chemical profiling was performed. The hydroethanolic extract (HeECf) and ethyl acetate (EA) fraction were assessed in multimodel systems with different levels ...

Bench to Any Side—The Pharmacology and Applications of Natural and Synthetic Alkylated Hydroxy Cinnamates and Cinnamides

Compounds
Natural alkylated hydroxy cinnamates (AHCs) isolated from medicinal plants and the thereby designed and synthesized cinnamides are derivatives of hydroxy cinnamic acids such as p-coumaric, sinapic, ferulic, and caffeic acids, which are naturally derived ...

Purification of α,β‐Unsaturated Carboxylic Acids as Their Potassium Carboxylate Salts Using Dry Column Vacuum Chromatography

Chemistry–Methods, Volume 6, Issue 5, May 2026.
Isolation of α,β‐unsaturated carboxylic acids from mixtures containing phosphine oxides (formed in Wittig‐type reactions) using standard procedures resulted in unsatisfactory outcomes in terms of product yield and/or purity. A new method involving purification of the products as their carboxylate salts using dry column vacuum chromatography enabled the

Comparative Phytochemical and Fatty Acid Profiling of Flax (Linum usitatissimum L.) Cultivars Across Diverse Geographic Origins

European Journal of Lipid Science and Technology, Volume 128, Issue 5, May 2026.
Flax varieties differ in growth, oil quality, and beneficial compounds, but these differences are not always clear‐cut. In this study, 10 flax types were grown under the same conditions and compared for plant traits, natural compounds, and oil content. Some showed high omega‐3 and lignan levels, making them valuable for healthier foods and future crop ...
