Recent Advances in Intramolecular C─N Bond Formation for Pyrrolidine Synthesis. [PDF]
ChemistryOpenThis review highlights synthetic advances (2013–2025) in intramolecular C─N bond formation for constructing the pharmaceutically relevant pyrrolidine core. The review is organized into five methodological clusters: 1) intramolecular alkene/alkyne amination; 2) tandem annulations, which involve C─N bond formation as the key step; 3) nucleophilic ...

The Effect of Thiocyanate Concentration on Thiocyanate Distribution and Excretion
Experimental Biology and Medicine, 1971 SummaryIt has been observed in rats that the measured volume of distribution of thiocyanate is decreased by high plasma concentrations of thiocyanate, and that large doses of thiocyanate have a faster rate of disappearance from the plasma than does endogenous thiocyanate at normal concentrations. These observations are interpreted as results of (i) the

Mechanochemical Approach for Metal-Free Regioselective C5-Sulfenylation of Imidazo[2,1-b]Thiazoles. [PDF]
ChemSusChemThis study presents a mechanochemical approach for the metal‐free, regioselective C5‐sulfenylation of imidazo[2,1‐b]thiazoles using bis(trifluoroacetoxy)iodo]benzene and aryl methyl sulfides. The method, performed under solvent‐free ball‐milling conditions, provides an efficient, environmentally friendly alternative to conventional synthesis, achieving
