description

Die Weidenhagen-Synthese N-unsubstituierter Imidazole aus α-substituierten Carbonylverbindungen 1, Aldehyden 3, wasrigem Ammoniak (4) und Kupfer(II)-salzen als Oxidationsmittel ist in Gegenwart primarer Amine 5 auch zur Darstellung N-substituierter Imidazole 6 geeignet. Weidenhagen Synthesis of N-Substituted Imidazoles The Weidenhagen synthesis of N-unsubstituted imidazoles from α-substituted carbonyl compounds 1, aldehydes 3, and aqueous ammonia (4) with copper (II) salts as oxidizing agents is also usable for the synthesis of N-substituted imidazoles 6 through the addition of primary amines 5.
