Asymmetric Catalytic Hydrogenation toward a Value‐Added Chiral Building Block: Optically Active γ‐Butyrolactone Scaffold from Renewable and Synthetic Derived Feedstocks

European Journal of Organic Chemistry, Volume 29, Issue 3, January 22, 2026.
This brief compendium summarizes the most successful asymmetric hydrogenation strategies for the preparation of chiral monocyclic γ‐lactone derivatives from keto acids and keto esters, with emphasis on their relevance for large‐scale production and high enatioselectivities. This article provides a brief compendium on the production of chiral monocyclic

Tuning the Circularly Polarized Reflection from Cholesteric Hydroxypropyl Cellulose Using Molecular Photoswitches

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Molecular photoswitches dispersed in a cholesteric hydroxypropyl cellulose mesophase enable reversible, light‐driven tuning of structural color and polarization. Enantiomer‐specific effects and light‐responsive patterning highlight the potential of dynamic, cellulose‐based photonic materials.

Synthesis of Enantiopure [3]Cyclorubicenes

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Herein, we present a high yielding synthesis of enantiopure [3]cyclorubicene, which is a potential precursor for a Haeckelite nanotube. This macrocycle was studied for its electronic and chiroptical properties and exhibits one of the highest dissymmetry values reported for a nanohoop.

EPR of High‐Spin Co(II) in Fully‐Chelated Octahedral Environments: From Solid State to Frozen Solution

European Journal of Inorganic Chemistry, Volume 29, Issue 2, January 12, 2026.
Five 6‐coordinated Co(II) complexes, with only chelating ligands, was examined by EPR in the solid state and in solution, at low temperature. Through simulations and density functional theory (DFT) calculations, the dramatic changes in spectral appearance that accompany dissolution can be attributed to structural dynamics rather than changes in ...
