N-(2-Aminobenzoyl)benzotriazole mediated and t-BuOK promoted synthesis of 2-substituted quinolone 3-carboxylates

Abstract

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
