N-(2-Aminobenzoyl)benzotriazole mediated and t-BuOK promoted synthesis of 2-substituted quinolone 3-carboxylates
Kökten, Şule; Çelik, İlhami (Pergamon-Elsevier Science LTD, 2015)2-Substituted quinolone 3-carboxylates were obtained in moderate to good yields by the reaction of N-(2-aminobenzoyl)benzotriazoles with beta-ketoesters in the presence of t-BuOK in THF -
N-(alpha-Amidoalkyl)benzotriazole-mediated synthesis of beta '-amido beta-diketones: a general synthetic protocol for N-[beta-(3,5-di and 1,3,5-trisubstituted pyrazol-4-yl)alkyl] amides
Çelik, İlhami; Kanışkan, Nevin; Kökten, Şule (Pergamon-Elsevier Science LTD, 2009)Various beta '-amido-beta-diketones were first synthesized with N-(alpha-amidoalkyl)benzotriazole-mediated amidoalkylation of 1,3-diketones in moderate yields. These intermediates undergo rapid condensation with hydrazines ... -
