Abstract
Synthesis of benzopyrano[2,3-c] pyrazoles and 3-triazolonyliminocoumarins was successfully performed using heterocyclization of 3-cyano iminocoumarin or their N-ethoxycarbonylated derivatives with semicarbazide reagents. Elemental analysis, infrared, and H-1 NMR spectral data confirmed the molecular structure of the newly synthesized compounds.
