Novel Bioactive Multifunctional Polyphenols: A Chemo‐Enzymatic Approach

Chemistry – A European Journal, EarlyView.
One‐step synthesis of complex alkyl oxystilbenin glucosides (6‐47% yield) in alcoholic medium. Switching to ter‐BuOH as solvent afforded δ‐Viniferin diglucoside, with high selectivity and high yield (> 90%), that can be upgraded by enzymatic esterification to alkyl δ‐Viniferin diglucosides.

Acid‐Catalyzed Synthesis of Si‐Stereogenic Silanes

Chinese Journal of Chemistry, EarlyView.
Si‐stereogenic silanes are important structural motifs in chemical synthesis, medicinal chemistry, and materials science. However, their catalytic enantioselective synthesis has largely relied on transition‐metal catalysts. Recently, Brønsted acids have been developed as promising alternatives.

Anisotropy Factor Spectra for Weakly Allowed Electronic Transitions in Chiral Ketones

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Anisotropy factor spectra for the weak n→π*‐type A‐band of chiral ketones cannot be described within the Franck–Condon approximation. Thus, we present such spectra computed by accounting for Herzberg–Teller corrections and compare them to experiments for fenchone, camphor and 3MCP to describe chiroptical properties of these molecules in the mid to near

Efficient Enantiomeric Selectivity Separation Via Homochiral Graphene Oxide Membrane

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A new type of chiral graphene oxide (GO) membrane is proposed that exhibits a separation factor of up to 20.1 as well as a preferential enantiomer flux of 4.5 mmol m−2 h−1. Moreover, the only first FPLC‐compatible column has been further developed via stacking these chiral GO membranes.
