Formation of 6-aryl-2-methyl-4-oxo-N,N’-diphenyl-2-cyclohexene-1,3-dicarboxamides from acetoacetanilide and aromatic aldehydes catalyzed by a mixture of aryl amines and iodine

Abstract

Reactions of acetoacetanilide with aromatic aldehydes in ethanol at room temperature in the presence of molecular iodine and arylamine afford to 6-aryl-2-methyl-4-oxo-N,N’-diphenyl-2-cyclohexene-1,3-dicarboxamides. The structure of obtained compounds was confirmed by mass spectrometry, IR and NMR spectroscopy data.
