Direct Access to α,β‐Unsaturated γ‐Lactams via Palladium‐Catalysed Carbonylation of Propargylic Ureas.

Advanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Additive carbonylations typically necessitate strong nucleophiles, such as alcohols or amines. In this study, we carbonylated a poorly nucleophilic urea, under oxidant‐free conditions. Our straightforward carbonylative strategy enables access to versatile α,β‐unsaturated γ‐lactams featuring an aminocarbonyl fragment, utilizing readily ...

Fluorescence Label‐Free Doxorubicin Sensor Using Polystyrene Sulfonate as a Synthetic Receptor in Whispering Gallery Mode Microresonators

Advanced Sensor Research, EarlyView.
The illustration showcases resonant optical microsensors for Doxorubicin (DXR) detection, using polystyrene sulfonate (PSS) as a synthetic receptor. PSS is deposited as a nanometer‐thick layer on fluorescent microparticles via layer‐by‐layer assembly. DXR‐PSS interaction is depicted, highlighting its effect on the sensor's resonant modes.
