1,4-Diaza-bicyclo[2,2,2]octane as a novel and efficient catalyst for the synthesis of 3,4,6-trisubstituted 2-pyridone derivatives

Heravi, Majid M.,Tahershamsi, Leili,Oskooie, Hossein A.,Baghernejad, Bita

, p. 670 - 672 (2010)

3,4,6-Trisubstituted 2-pyridone derivatives have been synthesized in good to excellent yields through a condensation reaction of various 1,3-diketones with amides in the presence of 1,4-Diaza-bicyclo[2,2,2]octane (DABCO) at reflux temperature.
