Determination of the second-order 1H NMR parameters for the aromatic protons in 4-fluoroaniline and application to the analysis of the 1H NMR spectra for the aromatic protons in N4-(4′-fluorophenyl)succinamic acid and in N4-(4′-fluorophenyl)-3,3-difluorosuccinamic acid

Unusual Oxidative Dimerization in the 3-Aminothieno[2,3-b]pyridine-2-carboxamide Series

Noncatalyzed, regio- and stereoselective hypochlorite oxidation of 3-aminothieno[2,3-b]pyridine-2-carboxamides is presented. Unexpectedly, the oxidation proceeded by different mechanistic pathways, and different products were formed, depending on the nature of solvents used. A possible mechanism, the structure of products, kinetics and dynamics of intramolecular processes, and biological activity of products are discussed.
