Synthesis of 4,N-diaryl-2-methyl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxamides
摘要:
Cyclohexane-1,3-dione reacted with substituted benzaldehydes and N-arylacetoacetamides in the presence of ammonium acetate under solvent-free conditions (150-160A degrees C, 10-20 min) to give the corresponding 4,N-diaryl-2-methyl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxamides. The product structure was determined by IR and (1)H NMR spectroscopy and mass spectrometry.
