Small, EarlyView.Dual circularly polarized luminescence (CPL) is demonstrated in pioneering metal‐free organic nanoparticles (ONPs) from a brominated trityl radical derivative. CPL activity in the Vis or NIR regions in aqueous environments is achieved by tayloring the content of radical enantiomers in ONPs, thanks to the generation of intrinsically chiral excimers ...

Angewandte Chemie, Volume 138, Issue 3, 16 January 2026.We report herein the development of catalytic asymmetric synthesis of secondary alkyl boronates. Under the optimal conditions, Cu‐catalyzed semi‐reduction of 1‐alkyl‐ or 1,3‐dialkyl‐substituted 1‐boryl‐1,3‐butadienes forms secondary alkyl boronates with excellent regioselectivities and enantioselectivities.

Development of an Efficient Stereoretentive Para‐Claisen‐Cope Rearrangement
ChemistryEuropeA stereoretentive para‐Claisen‐Cope rearrangement of chiral aryl‐allyl ethers is reported, achieving near‐perfect chirality transfer thereby furnishing products with exceptional enantiomeric excess (up to > 98% ee) as single regioisomers.

New Phytologist, EarlyView.Summary Plant‐derived oils are essential sources of reduced carbon and various fatty acid (FA) structures for food, biofuels, and the oleochemical industry. Despite extensive efforts, engineering mainstream oilseed crops to produce high levels of industrially valuable unusual FAs (UFAs) remains challenging.

Angewandte Chemie, Volume 138, Issue 3, 16 January 2026.The structural transition between the two fully‐characterized states of a supramolecular helical hydrogen‐bonded polymer (represented as blue and light pink stacks) can be predictably varied over 85 K by changing the nature and amount of cosolvent; entropy of solvation (schematized as solvents of different sizes) is the main lever to tune the ...
