Visible‐Light Mediated Activation of 1,3‐Dienes and Allenes via Energy Transfers

Chemistry – A European Journal, EarlyView.
Nature has inspired chemists to develop photocatalytic processes that harness visible light, offering alternative reaction pathways beyond traditional thermal methods. Energy Transfer (EnT) is a particularly promising strategy, enabling transformations such as isomerization, deracemization, cycloadditions, and cascade reactions.

4‐Dimethylamino‐1,8‐Naphthalimide as a Fluorescence Signal Amplification for Site Selective and in Situ Probing of the Hydroxyl Radical

Chemistry – A European Journal, EarlyView.
4‐dimethylamino‐1,8‐naphthalimide (NMI) as new fluorescence‐responsive tool for HO• detection. Proof of concept illustrating that NMI selectively probes HO• produced by Cu‐bound to Aβ16 in presence of scavengers with an amplified response. Abstract Overproduction of reactive oxygen species (ROS) is involved in several diseases.

Deuteration of Six‐Membered N‐Heteroarenes: Chemistry and Applications

Chemistry – A European Journal, EarlyView.
Deuterated six‐membered N‐Heteroarenes (6NHetAr) are finding utility in an increasing repertoire of applications. Our paper comprehensively reviews synthetic approaches that have been reported for the deuteration of 6NHetAr and their fused counterparts while providing an overview of established and emerging applications for these materials.

Pharmaceuticals Made with Hydrogen: A Sustainable and Efficient Approach Using Flow Synthesis

Chemistry – A European Journal, EarlyView.
We demonstrate a sustainable strategy for pharmaceutical manufacturing by combining hydrogen, heterogeneous catalysis, and continuous flow synthesis. The development of novel catalysts and their application in a multi‐step synthesis of donepezil enabled a highly productive process with no intermediate purification.

The stereochemistry of the addition of chlorotitanium enolates of N-acyl oxazolidin-2-ones to 5- and 6- membered N-acyliminium ions

Journal of the Brazilian Chemical Society, 2001
The stereoselective addition of chiral and achiral titanium enolates derived from the corresponding N-acyl oxazolidin-2-ones to 5- and 6- membered N-acyliminium ions afforded 2-substituted pyrrolidines in moderate to good diastereoisomeric ratio (5:1 to ...
