An efficient method for the synthesis of 2,4,6-triaryl-pyridinesvia microwave-promoted and BF 3 ˙OEt 2 -catalysedone-pot reaction of ω-pyrrolidinoacetophenone with chalconeis reported. This method illustrates urea as an environmentallybenign source of ammonia for the synthesis of 2,4,6-triarylpyridines.
2,4,6-Triarylpyridine derivatives were synthesised by the reaction of guanidine with an acetophenone and a chalcone. These reactions were carried out as economical one-pot reactions under green conditions: no catalyst and solvent free.
