Insights on Regioselective Synthesis of Fused Thiazoles: Density Functional Theory Calculations, Local Reactivity Indices, and Molecular Electrostatic Potential Analysis

ChemistryOpen, EarlyView.
A regioselective synthesis of fused thiazoles was achieved via aza‐Michael cyclization of thiazolidinone derivatives with hydrazines or heteroaryl amines. Density functional theory, local reactivity indices, and molecular electrostatic potential mapping are used to explain selectivity.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Cationic Polyelectrolyte Adsorption onto Anionic Nanoparticles Analyzed with Frequency‐Domain Scanning Fluorescence Correlation Spectroscopy

Small Methods, EarlyView.
A small‐circle scanning fluorescence correlation spectroscopy (sFCS) technique is presented using acousto‐optical laser scanning and frequency‐domain fitting. Validated with simulations and experiments, sFCS investigates cationic polyelectrolyte adsorption onto anionic nanoparticles, revealing stable complexes and size increases with polymer mass ...
