The modification of N-phenyl-aza-15-crown-5 (PA15C5) and N-(4-aminophenyl)-aza-15-crown-5 (4APA15C5) on glassy carbon (GC) electrode was performed by the electrochemical oxidation of the corresponding azacrown derivatives in anhydrous acetonitrile media. The electrochemical behavior of the ...
Crown ethers (CRs) are one of the generally used host molecules to increase selectivity of heavy metal ions (HMIs) in electrochemical analysis. To study the cavity size and geometry induced ions selectivity change in naphtho-aza-crown ethers (NACEs), three novel rigidified NACEs have been ...

The electroreduction or chemical reduction with zinc powder has been found to be effective to intramolecular coupling of aromatic diimines yielding 1,4-diazacrown ethers. The latter reduction was particularly effective to formation of 1,4-diaza-12-crown-4 derivatives due to the template effect of...

A short and highly efficient route to sugar-aza-crown(SAC)ethers has been developed.The key step of the transformation is a one-pot cyclodimerization of C-glycosyl azido aldehydes via a domino Staudinger aza-Wittig reaction.This process allows the preparation of various orthogonally protected SAC ...
