The Structure of Carboxyl Methyltransferase Provides Insights Into the Substrate Specificity and Divergent Evolution of Iridoid

open access: yesPlant Biotechnology Journal, Volume 24, Issue 6, Page 3708-3722, June 2026.
ABSTRACT Iridoids constitute a prominent class of plant‐specialised metabolites, with carbocyclic iridoids (e.g., geniposide) and secoiridoids (e.g., loganin) diverging early in their biosynthetic pathways. This divergence is marked by substrate‐specific carboxyl methyltransferases—GjGAMT and CrLAMT—that catalyse the decisive methylation step in ...

Metal Nanoparticles on Halloysite Applied in Stereoselective Hydrogenation of Tetrasubstituted Alkenes

open access: yesChemistry – A European Journal, Volume 32, Issue 20, 27 May 2026.
Composite materials based on metal nanoparticles supported on a naturally occurring nanotubular clay, halloysite (HAL), led to the diastereoselective hydrogenation of tetra‐substituted alkenes under relatively smooth conditions, mainly oxazolidinone‐based heterocycles.

Better Material Properties and Faster Catalyzed Chemical Recycling for Poly(L‐Lactide) Using a Simple Commercial Glycerol Ethoxylate Additive

open access: yesChemistry – A European Journal, Volume 32, Issue 20, 27 May 2026.
Glycerol ethoxylate (GEO), a branched ethylene glycol derivative, both toughens commercial PLLA and accelerates its chemical recycling to L‐lactide. The lead sample, containing 10 wt.% GEO, shows 9x higher elongation at break and 6x higher tensile toughness than pure PLLA. The GEO–PLLA samples are efficiently chemically recycled to L‐lactide, even when

Chiral Bicomponent Melamine/Amino Acid Eutectogels: Efficient Catalysts for the Aldol Reaction

open access: yesChemSusChem, Volume 19, Issue 10, 27 May 2026.
Chiral bicomponent eutectogels were used as confined reaction media for stereoselective aldol reaction between cyclohexanone and p‐nitrobenzaldehyde, proving efficient and reusable catalysts. Supramolecular gels, characterized by reversibility, stimuli responsiveness, and high surface area, represent a promising class of materials in catalysis. In this

Photochemical Decatungstate‐Catalyzed Hydroacylation of Maleimides

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 20, 27 May 2026.
A photocatalytic protocol to access substituted succinimides via tetra‐n‐butylammonium decatungstate photocatalysis is reported. This direct radical‐driven hydroacylation of a variety of N‐substituted maleimides shows tolerance to various aldehydes (or alkanes), affording differentially substituted succinimides in high yields. Succinimides constitute a
