Interfacial Photoelectrochemistry in Organic Synthesis

open access: yesAngewandte Chemie International Edition, Accepted Article.
Photoelectrodes have traditionally enjoyed widespread attention as heterogeneous catalysts for the activation of water and CO2 in energy research, while photoelectrochemistry with homogeneous molecular catalysts dominates the activations of more complex molecules in organic synthesis.

Combined Inductive and Dispersion Effects Enhance Bioorthogonal Reactivity of Tetrazines Toward Isonitriles

open access: yesAngewandte Chemie International Edition, EarlyView.
Bulky, electron‐withdrawing substituents can significantly enhance the reactivity and stability of tetrazines toward isonitriles, addressing a key challenge in bioorthogonal chemistry. This study explores the role of frontier‐orbital interactions, dispersion forces, and molecular conformation in optimizing tetrazine performance, leading to highly ...

Antiprotozoal Activity of Highly Substituted Pyrazole and Pyrimidine Derivatives. [PDF]

open access: yesChemMedChem
Based on previously identified antimalarial agents, a series of highly substituted pyrazole and pyrimidines derivatives has been synthesized and tested for antiplasmodial and antileishmanial activity. Selected derivatives show promising antiplasmodial effect with a predicted favorable pharmacokinetic profile.

Expanding the Repertoire of Photoswitchable Unnatural Amino Acids for Enzyme Engineering

open access: yesAngewandte Chemie International Edition, EarlyView.
Enzyme engineering with photoswitchable unnatural amino acids (psUAAs) has a high potential for applications such as biocatalysis. Here, we extend the current repertoire of psUAAs to include more versatile properties paving the way to more advanced photocontrol engineering.
