    Description / Table of Contents: Chemistry of Nitrosamines, V. - Syntheses of α-Functional N-Nitrosodialkylamines: Thioethers and DithiocarbamatesThe in vivo reaction products of electrophilic compounds with glutathione are excreted as S-alkyl-N-acetylcysteins (mercapturates) after enzymatic degradation. The results clearly show that mercapturates as 1-substituted N-nitrosodialkylamines 11 are chemically stable enough to be isolated and characterized. The reactions of 1-chloro-N-nitrosodialkylamines 5 with 3,4-dichlorothiophenol, ethanethiol, and N,N-diethyldithiocarbamate illustrate the high tendency of formation of 1-thiosubstituted nitrosamines.
    Notes: S-Alkyl-N-acetylcysteine (Mercapturate) werden als enzymatische Abbauprodukte der Reaktion von Glutathion mit elektrophilen Verbindungen im Organismus ausgeschieden. Es wird gezeigt, daß Mercapturate als 1-substituierte N-Nitroso-Verbindungen 11 synthetisch zugänglich und stabil sind. Durch die Umsetzungen von 1-Chlor-N-nitrosodialkylaminen 5 mit weiteren Schwefelnucleophilen wie 3,4-Dichlorthiophenol, Ethanthiol und N,N-Diethyldithiocarbamat läßt sich die große Bereitschaft zur Bildung von 1-thiosubstituierten Nitrosaminen aufzeigen.
