Characterization of Grape Cane Stilbenoids and Their Photo‐Degradation Products by HPLC‐DAD Coupled With Trapped Ion Mobility Spectrometry and High‐Resolution Tandem Mass Spectrometry

Rapid Communications in Mass Spectrometry, Volume 40, Issue 15, 15 August 2026.
ABSTRACT Rationale Bioactive (E)‐stilbenoids in vine extracts are prone to light‐induced transformation into the respective (Z)‐isomers and further degradation products, often resulting in a loss of bioactivity. We sought to study stilbenoid degradation beyond that of the well‐researched resveratrol due to the high diversity of stilbenoids in nature ...

A Green and Highly Selective Approach to Copper‐Catalyzed Transfer Hydrodeuteration of Alkenes and Alkynes Using D2O

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
Highly selective deuteration is now possible with a green and more environmentally benign reaction protocol for Cu‐catalyzed transfer hydrodeuteration of alkenes and alkynes. This was applied to the synthesis of precisely deuterated alkanes, including deuterated complex molecules and high enantiopurity isotopomers. Precisely labeled small molecules are
