Chinolin synthese

WebThe Bischler–Napieralski reaction is an intramolecular electrophilic aromatic substitution reaction that allows for the cyclization of β-arylethylamides or β-arylethylcarbamates. It was first discovered in 1893 by August Bischler and Bernard Napieralski [], in affiliation with Basle Chemical Works and the University of Zurich.The reaction is most notably used in … WebA set of quinoline coupled triazole derivatives was synthesized using substituted quinoline hydrazide and isothiocyanate derivatives. The structures of the synthesized molecules were confirmed using spectral techniques like FTIR, 1 H & 13 C NMR spectroscopy. Novel triazole thione derivatives were subjected to anticancer and antioxidant activity.
