Several new annelated pyrazole, 3H-quinazolinone and thiazole derivatives are synthesized via the reaction of 2-bromothienylglyoxal-2-arylhydrazones with different reagents.The structures of the newly synthesized compounds were established on the basis of elemental and spectral data studies.Key words: Pyrrolopyrazoles; pyrazolopyrimidines; coumarines; 3H-quinazolinones; pyrazoles; thiazoles.
