The new
tri-enaminone, namely,
3,4-bis(3-dimethylamino-2-propenoyl)-1-[4-(3-dimethylamino-2-propenoyl)phenyl]-5-methyl-1H-pyrazole was prepared and used as building block for synthesis of novel polyaza-heterocycles. The latter compounds were obtained
via an efficient
one-pot reaction of the
tri-enaminone with 1,3-dipoles and various electrophilic and
nucleophilic reagents. The structures of the new products were confirmed based on elemental and spectral analyses. Also, alternative synthetic methods were carried out wherever possible as further evidence for some of the newly synthesized products.
